Video Transcript for Blue Ox Tow Bar Wiring Kit Installation - 2020 Jeep Gladiator

Hi there Jeep owners. Taking your 2020 Jeep Gladiator, we're going to be taking a look at and showing you how to install Blue Ox Diode wiring. A diode wiring kit is going to take all the lighting signals from your motor home and transfer them to the lights at the back of your vehicle. This way, when you're flat towing, people behind you will know your intentions when going down the road. This includes your left turn signal, right turn signal, tail lamps, and brake lamps, keeping you DOT compliant in all states as well. There's five main components you'll need when flat towing your vehicle behind your motor home.

You'll need your tow bar, which is the connection between your motor home and your vehicle. Your safety cables, which is a supplemental connection in addition to your tow bar in the event of a catastrophic disconnect. You'll also need your base plate which provides a connection point on your vehicle for your tow bar and safety cables to attach to, as well as, often places for your wiring as well. You'll also need your diode wiring which will take all the lighting signals from your motor home and transfer it to your vehicle, so people behind you will know your intentions when going down the road. And your supplemental braking system, which will apply the brakes in your vehicle when you hit them in your motor home to help you come to a smooth and safe stop.

Some other options beside diode wiring is bulb and socket kit, which would install an additional bulb inside your assembly that you have to drill a hole to add it. But that's really not an option on most modern vehicles with LED lights because there's not room inside for them. Another option would be magnetic lighting, where you can just stick those to a magnetic surface on the vehicle and then run a cable up to the front so you can plug it into your motor home. The only problem with these is that you have to set it up every single time you want a flat tow, you got to get those out put them on, and plug it in around that wire and on some vehicles you may have issues finding a good magnetic surface. The main reason that I prefer diode wiring over any other system is because it uses the factory lights on our vehicle, so it's one of the cleanest looks, it's ready to use every time you want to use it.

You just simply plug it in once you've done the install. And the diodes also protect your vehicle from any of the current that's coming from your motor home. It directs it to your lights and it acts as a one-way check file for electricity, so it can't come from your motor home and then back feed down to your computer systems and damage your vehicle. I also like this type of system because if you're going to install a braking system, many different systems out there require tapping into the diode or the lighting systems to get your brake signal. So this will help you out in that as well.

Now, this diode wiring kit does not come with a connection solution here at the front, it just comes with the bare wires. The most common is a 6-pole that you'll see here, which you can purchase separately here at etrailer. And if you pay attention to your tow bar, some tow bars do come included with the 6-pole connector, so you may not even need to purchase another one. Another option is adding a 4-pole connector here at the front. That's not as traditional, as it's only going to give you your lighting signals. So I do highly recommend going with the 6-pole instead, so you've got options for additional accessories that you can place in there, such as a charge line kit. Now that we've gone over some of the features why don't you follow along with me and we'll show you how to get it installed. We'll begin our installation underneath the vehicle here at the back. We can actually access our tail light wiring without removing the tail lights because they're right here down below. And we're just underneath the vehicle here at the back corner on the driver's side. And as you can see here, this is the wiring that goes up to the tail light, so we can actually tap into it right here. I just took my razor knife and I cut back some of the sheathing here and I just peeled it off to reveal all the wires. Once we've got it exposed we can get the wires that we need. We want the yellow wire, that's going to be our stop turn circuit for the driver's side here. And we also want the white wire with the gray stripe, But this is where it does get a little tricky because you'll notice there is another white wire with a gray stripe in here. This one is a smaller diameter wire though. If we hold both of these next to each other, you can see that one is a smaller diameter, smaller gauge wire than the other. We don't want the small one. The small one is for a sent circuit, so it can determine if the bulbs are working properly. We want the one that's thicker. So we've got those two isolated by themselves, we can go ahead and cut both of these wires. Once you've got them cut, we're going to strip back each end of these wires so we can crimp on the female spade terminals that come included with our kit. Now that we've got them all stripped back we're going to take the female spade terminals that come in our kit, we're going to slide it over the end of the wire and then, crimp it on. We're going to repeat that for each of these wires. So now we can take the 4-pole harness that comes in our kit, gone ahead and taken off the wrappings that had it wound up and on the ends here, we need to separate these out. We're only going to be using the yellow, brown, and white on the driver's side here and we're going to be using the green on the passenger side. Now you do get extra green and brown wire in your kit because our brown wire here, we need to actually go over to the passenger side as well. We need both those circuits. We're going to be using a section of the white wire though because we've got plenty of length here so we can go ahead and use what's here already. So what we'll be doing is taking our snips, we're going to cut the green wire to separate it and we're just going to peel this back. We're going to need to peel this back enough to where our yellow wire here can reach over to this side. and the green wire can reach all the way over to the other side. We don't need to peel that all the way for now, you can do that here in a little bit. We do want to get that out of the way because we don't need it over here. The remaining three wires here, we are going to take and cut the same way, but we're going to have all these wires over here, so we're just gonna peal these back just a little bit, just enough so that we can work with them over on the driver's side here, so about that far is probably good. We're gonna then, strip back each one of these three wires here. And then, I'm gonna go ahead and wrap the wire up towards there a little bit. We're going to go over a few things just so I've got the wires over here on this side. And then, we can make our connections up here and get them hooked in. I've got our wires routed over here to the driver's side. I went ahead and put the green wire over towards the passenger side. The yellow wire, we're going to take one of our spade terminals and we're going to crimp that onto our yellow wire. And then, the brown and the white wire here, we're going to be using a small section of this white wire to jump the brown circuit over to the passenger side. And the easiest way that I found to do this is when you take your wires here and stretch them out, you're green to one side and your yellow to the other. If you take the green and kind of fold it back down the harness from where you'd peeled it back and see where the green wire ends on the harness that's where I cut the white wire and then, I can use a section of this to run over to the other side. So that means, both of these wires here need to be hooked together. And this can be a little tricky because the spade terminal that you get included with your kit is just barely large enough to slide over two wires. But if you twist them like that and then, when you take your spade terminal if you also twist it while pushing it on you can usually get them to all fit inside that one terminal. We'll then crimp these down and we're ready to make our diode connection on the driver's side here. If we look at our diode up close, you'll see it is labeled, Out and In. Out is always going to go towards our tail light assemblies and the In is going to be our vehicle and the wiring that we ran. So we're gonna go ahead and take our diode here. We're going to start with the yellow circuit, which is our stop and turn for the driver's side here, for the left side. So this is towards the assembly, the taillight assemblies. We're going to plug that into the Out. We're then, going to take our diode, we're going to bring it up here. We're going to take the yellow wire that we had cut the other end of it. This is going back towards our, the rest of our vehicle. We're going to plug that into one of the insides. Then, the harness that we had routed over here, we're going to take the yellow wire from it because that's our stop turn that we're routing, and we want to plug it into the other end. We'll then take our other diode and we're just going to repeat this procedure pretty much exactly the same. We're going to put the Out on our tail light wire towards the tail light housing. The other end of our tail light wire we're going to plug into the In, and then our white and brown wires that we'd connected here, we're gonna connect to the other side. Now, we've got these all connected up. You can go ahead and tape this back up and put some zip ties on it to clean it up. Then we're going to head over to the passenger side now where we've routed both the green wire and then a section of this white wire. So over here you can see on our passenger side, we routed over for both the green wire, as well as a section of that white wire. This is what's connected to the brown wire over on the driver's side. On this side, we do the same procedures but we have to cut different wires. We open up the harness and we're going to take the green wire, that's our stop turn for the passenger side, and the white wire with the orange stripe. It's easier on this side because there is no other wire that has the same color. So once you find these two, you know you've got the right ones. Our white wire that we'd run over is the tail light circuit, that's going to plug into the diode that has the white with orange wire and the green wire that we ran over as our stop turn circuit, so that's going to plug into the diode that has the factory green wires on it. You can see here where I taped it back up and then zip tied it to make sure that our diodes stay in place. So now, we've got all the connections made here at the back, we're going to start routing our wire towards the front. So we went ahead and went above our spare tire in here. Our wire kind of came out towards the center here, we zip tie it to any factory wiring along the way. We went above our spare tire and tried to stay above all the heat shields because we want to avoid anything excessively hot, like our exhaust, any moving components, like our steering or suspension. What we come out over our heat shield on the driver's side in front of the spare tire. Our factory harness is here, so we zip tied to that along the way. Keep going forward and you'll notice here that we've got the white wire here. This is where we had cut our white wire and used that section to make that jumper across. We're going to run this into the bottom of the vehicle right here. There's a nice support channel here underneath the bed that we can run right into. It's going to give us a good ground and since it's a channel we know we're not going to be drilling through the bed or into the vehicle or anything. So we can go ahead and take a break here for a second from running our wire and we're going to make this connection. So we're going to take the white wire here, we're going to strip it back and then, you'll get a single ring terminal that comes included with your kit. That's what we're gonna be crimping on here. There's our ring terminal, slides on just like that. Once we've got it slid on our wire we just need to crimp it down. I went ahead then and just took the included self-tapping screw, pushed it through the ring terminal and ran it right into that channel. I used a quarter inch drill bit to do so. One of the things I didn't like about this kit is this ring terminal here has an opening that's actually slightly larger than the ring terminal or than the self tapping screw that they give you. So you want to make sure you push that ring terminal off to one side so that way you get a good bite on it and make sure it doesn't rotate after you've tightened it down So we got our ground attached, we just continue going forward. We stay above the heat shield here, just above our muffler. And when we come out the other side of our heat shield here, we actually go right on top of the frame. We go over the top of the frame to the outside of the frame and there's an opening on the other side where we're actually going to go inside the frame. So here we are right on the outside, you can see where we went into the opening and from here we stay inside the frame going all the way up in the frame still until we get about to this point here. And then, we're going to come out the frame on the inside of the frame here. And here's where we come out the inside of the frame, we're pretty much right in line with the center of our wheel here. There's an open hole, that's where we come out. We then go up around the steering gear there, trying to make sure we can avoid anything that's moving, because here's the bottom of our steering gear, we wanted to stay away from that because this arm pivots. You can see where we come out next to the frame. We stay along the frame until we get in front of all of our moving components. And then we just drill a hole here at the front for our under shield and poked our wire through it. I then slid a little bit of wire loom on it just to help protect it and make it look nicer. If you need some wire loom, you can get some here at etrailer. And then, we come right out here in the front where we can mount up a 6-pole connector and get it attached, because the front of your wires are just going to be bare. We don't have anything here and you'll need a 4 or a 6-pole in order to connect to your motor home to get your lighting. A 6-pole is what I would recommend. That's going to have everything you'll need for wiring, for lights, as well as a couple of extra spots that you can use for accessories that are going to be useful later on down the road. Now, I did want to point out this large hole here in the frame. This is just behind the tire on the driver's side. We're installing an Air Force One supplemental braking system, which doesn't require diode wiring for the braking system to work properly, but many of the braking systems out there do require you to tap into your diode wiring for the system to work properly. If I was going to install or use one of those braking systems, I would have routed this wire up to the top of our engine compartment there so I could easily access those to make those connections. So what I would normally do if I was putting one of those breaking systems on is I would come up this large hole here. You can easily fold this fender liner back and then go straight up the back of the firewall and then you can just route your wire forward and then go back down to the front to reach the same place in the end, but it's much easier if you bring that wire up to install a braking system that taps into it. So we're gonna go ahead and show you how to hook up a 6-pole. If you we're doing a 4-pole it would be easy because 4-poles are already color-coded so you just match color to color, but a 6-pole is not that way. You'll also need a bracket to mount it on your Gladiator and many cases your base plate provides an attachment point, but the one we have here does not. So we went ahead and just use one of the pre-existing holes and another self-tapping screw to run a bracket up into here. You can get brackets here at etrailer as well. We're going to take, we're going to start off by taking some of this excess, we don't need all this. We're going to cut some of this off. I like to leave a little bit of excess here out the front just to make it easier to make our connections and if we had to do any testing or future repairs it all that just makes things a little bit easier. We can then take each of these wires and we're going to separate them similarly to how we did at the back and then we'll strip back each one once we get them all separated. So now, we've got those all separated and stripped, we can take the rubber boot that comes with our 6-pole connector. We're going to slide that on first, just like that. And then, we'll take our connector here and we're going to loosen up the screws for the appropriate circuits that we're going to be connecting. I like to start on the ground circuit, which is labeled GD. If you look there, those little labels, so we're going to loosen up GD for ground. Then, if we just give it a little spin next to that, we'll have LT, which is left turn, that's our yellow wire, ground was our white wire. Give it a spin again and then, it says RT. RT is our right turn signal, that's our green wire. Next, it says S. We're not going to use that one, we're going to skip. The next one says TM, that is our tail light wiring. That's our brown wire so we're going to use that one as well. The center pin, we're not going to use, but if you we're installing a charge line that's where that would attach. That's an accessory that I would recommend for most people flat-towing because that way, when you're flat towing you'll ensure your battery stays topped up when you're going down the road. So now, we're just gonna poke in our wires into the appropriate hole based on the labeling. So we're gonna go back to the one labeled ground that was white, we're then just going to poke it in and tighten our screw down and we'll just work our way around that circle attaching the appropriate wire to the appropriate connection point. Now, that we've got all of our connections made there, you can see all of our wires attached. We're going to take some dielectric grease and we're going to be real generous with it here on the backside of our connector. That's going to help seal this up and keep out any moisture, just help us ensure that we have a long lasting corrosion-free connection. And then, we'll slide our boot on it, and then, to keep our boot in place and to help seal in our grease, I'm going to tape up both the front and back side of our boot to our connector here. Then, I also like to tape up the backside as well. We can then just slide our connector into place. And then we're gonna go ahead and attach our 6-pole to the bracket using the hardware that came included with the bracket. So now that we've got our wiring completed, we want to go ahead and test everything out. You can plug into your motor home to do this at home. I plugged in a tester here at the front of the vehicle and you want to verify that all your lighting signals works. So operate your left turn signal, your right turn signal, tail lamps, and brake lamps. And with all of our lights working properly we're ready to hook our vehicle up to our motor home, put it in to flat tow and hit the road. And that completes our installation of Blue Ox Diode wiring on our 2020 Jeep Gladiator..

Blue Ox Tow Bar Wiring Kit - 4 Diodes - BX8848

Average Customer Rating:  4.7 out of 5 stars   (91 Customer Reviews)

Connect your towed vehicle's lighting system to your RV's to get the brake lights required for towing.

by:

The order arrived very quickly and is all intact. The (base plate) picture quality is a little poor from Blue Ox, but I talked to Angela B. and she is emailing the instructions to me for better viewing.
I might add that Blue Ox would have charged for shipping.
Now it is time for the installation.



by:

Customer Service is excellent! The tow bar was delivered promptly and should work great. I didn't receive the wiring kit I ordered but when the company was contacted....they were great to work with and shipped another right away!!



by:

The Blue Ox Tow Bar Wiring Kit - 4 Diodes work exactly as advertised. The diodes work to separate the harness from the system, so there is no back feed to the car's electrical system when the brakes, lights, or turn signals are activated in the motorhome. The car's rear lights are activated in sync with the motorhome lights. So much easier to hook up the "toad" to the motorhome using this harness.
Installation when very easy, after I figured out how to access the taillights on the 2019 Chevy Traverse, but now that's another story.
I would highly recommend this harness.

Im still loving it!

Still using magnetic lights. Haven't installed wiring kit yet.



by:

Everything needed to provide motorhome lighting to the towed vehicle. This will NOT eliminate towed vehicle battery drain on long tows, and while many have a way to boost towed vehicle battery during tows, no one seems to have the reason for the battery drain. I thought the diodes would eliminate that problem.

On time and correct items.

As always you sent me another great product for my RV it's always so easy with the instructions that are provided with your products and the quality is always top notch I really needed this to wire my TJ Sahara jeep for a tow dingy to drag around behind our motor home I was worried that wiring the brake lights, etc. the same as a trailer would have a detrimental effect on the jeeps wiring its nice to know that just looking it up on your website gave me all the info I needed and a choice of products Thank you

its still a great product even after a year and I am sure it will last many more years
Jim - 05/08/2018


by:

We love the Blue Ox kit! Pretty simple to use.



by:

Toughest part of installing this system was determining the best and neatest way to route the wires from front of the vehicle to the rear. Works great but does not provide wiring to run the third/middle brake light on the towed vehicle which in my case is a 2010 Chevy HHR. I subsequently opted to install a system which constantly charges the HHR battery from the RV power which allows me to keep the HHR power on so when the Brake-Buddy applies the brakes all the brake lights illuminate. Otherwise a perfectly good system with everything you need for an easy install.

Good price when ordered, fairly easy to install using your DIY video, and works well on the tow vehicle when pulled by our RV.



by:

Great and responsive service



by:

Our installer did a great job installing the wiring kit; all the lights work



by:

Easy install. One of the diodes was inoperative out of the box but etrailer resolved the issue quickly. Very appreciative of their excellent support.



by:

Easy installation and works as expected…. Quick, safe delivery…



by:

etrailer has always done me good. Their prices are very reasonable and the products are just what they say they are. Shipping is timely and free on if you spend enough.
Good place to shop.



by:

Went well except for instructions installing baseplate for my 2017 Silverado. After grille removal was not close to the instructions. I [looked for installation videos for] 2018 model and instructions for grill and bumper removal was right. Nice project and saved a lot on install. etrailer is great at putting together the equipment you need. Love website to research products. Have not pulled truck any where yet. [(Covid)]



by:

I am new to the world of towing a vehicle behind an RV and found a lot of articles/videos on the interweb, not having a clue what to expect except what I've read and watched on the web I reached out to etrailer.com and Courtney B answered all my questions, removed all my doubts of what i was doing and provided everything we needed in the timeframe we needed it at a reasonable price! I can't thank her or etrailer enough!!! I will buy here again and trust in they're how to videos without question. Thank you



by:

Secure and safe. Meets all our needs.



by:

Always excellent response and follow-up



by:

I was looking for a product that had everything I would need to do the job without having to go to local auto parts store to find special parts not usually stocked. The instructions were pretty good but could have been better with a couple of photos and details in the routing near the engine compartment and wire loom for added protection in the area. The finished look is well hidden as it should be and not hard to install.

  • Troubleshooting Diode Trailer Wiring Installed on Vehicle Where Turn Signal Flashes Both Sides
    It sounds like you have the turn signal and running light circuits ran backwards so that when either blinker circuit is activated you end up with both lights flashing. This is because the running lights run to both sides of the vehicle and the stop/turn circuits go to each side specifically.

  • How Does Blue Ox Diode Kit BX8848 Install on Vehicle With Separate Turn Signals Taillights
    On vehicles that have separate stoplights from turn signals you can wire up a diode kit like the part # BX8848 still but what you have to do is basically make the stoplights of the vehicle function as both the stop lights and turn signals since that is how the diode kit is wired. Trailer wiring puts these circuits on same wire which is why it's easiest to do diode tow bar wiring the same. Basically your current stoplights will still function as stoplights but they will flash with the blinker...

  • Compatibility Of Blue Ox Wiring And Diodes With 2020 Ford Edge
    The Blue Ox Tow Bar Wiring Kit - 4 Diodes # BX8848 will absolutely work with your 2020 Ford Edge. The Blue Ox 6-Pole, Round Pin, Trailer Wiring Socket - Vehicle End # BX294-0902 is my recommendation to go along with this kit to give you the connection on the front of your vehicle. You will also likely want the Roadmaster Automatic Battery Disconnect with Switch for Towed Vehicle w/ Supplemental Braking System # RM-766 to conveniently disconnect your battery as required for flat towing.

  • Why is RoadMaster Tail Light Wiring Kit # RM-155 Not Recommended For a 2011 Chevrolet Malibu LT
    Neither one of our manufacturers, RoadMaster or Blue Ox, recommend to use the bulb and socket type of lighting when flat towing a 2011 Chevrolet Mailbu LT. Usually it is because of limited space in the taillight housing that does not allow the bulb and socket to fit properly. We go by what the manufacturers recommend, since they have already done a test fit on the vehicle. The RoadMaster Diode Wiring Kit, part # RM-154, or the Blue Ox Wiring Kit, part # BX8848 is recommended for your Malibu. I...

  • What is the Correct Diode Kit to Flat Tow a 2007 GMC Sierra 1500 New Body Style
    I show that for a 2007 GMC Sierra 1500 new body style, you will need to use the Roadmaster 4-diode kit, # RM-154. Your truck has a 2 wire system (combined brake and turn circuit) so additional diodes are not needed. There are diagrams on the product page, below the description, for wiring the diodes, and I have also included the pictures here. If the towing vehicle has a combined brake and turn circuit, you will use the first diagram. If the towing vehicle has separate brake and turn...

  • How Does the Blue Ox Patriot 3 Activate Brake Lights On 2020 Chevy Equinox With Diodes
    The Blue Ox Patriot 3 Radio Frequency, Portable Braking System part # BRK2019 does not tie into the stop light circuit on the vehicle, it would operate independently of the Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit part # RM-15267 (Premier Models Only). The diodes would prevent both the towed vehicle and tow vehicle from both sending power to the tail lights on the towed vehicle.

  • Can the LED Bulb and Socket Kit # BX88267 be Installed on a 2009 Subaru Forester for Flat Towing
    We do have an LED wiring kit just like the Kit # BX8869 that you referenced. It is found as part # BX88267 on our site. You can use the LED kit if your 2009 Subaru Forester does not have LED tail lights and if each tail light housing has enough room for an extra bulb and socket. It could be that there is no room for an extra bulb and socket which would be why the Roadmaster Kit # RM-152-LED isn't confirmed to fit.
