How to Install the Hopkins Tail Light Wiring Kit on a 2010 Jeep Wrangler


Ryan: How's it going Ryan here at etrailer.com. Today, on our 2010 Jeep Wrangler, we're going to be taking a look at and showing you how to install the Hopkins Custom Tail Light Wiring Kit for Towed Vehicles.Now the purpose of the wiring is to transfer the lighting signals from the back of your motor home to the back of your Jeep. That's not only going to keep you legal, but it's going to allow other motorists to know what your intentions are as you go down the road. Now one thing I like about this kit is that it's going to have built in diodes, which are going to protect your Jeep's factory wiring if a short or an electrical issue we're to occur on your motor home side.Now the wiring is going to come pre-attached at the front end with a four pole flat connector. Now what I recommend doing, like we did on our Jeep, is actually upgrading to a six way round connector like we have here. And that's just going to give you a little more options to run other accessories like a charge line kit for example.

And it's just going to be a little easier to make that connection from the front of the Jeep to the back of your motor home.As far as the lighting functions that we're going to get from the back of the motor home to the back of the Jeep will be our brake lights, our left turn signal, our right turn signal, and our running lights. Now keep in mind our wiring is just one of five main components needed to flat tow our Jeep down the road. The other four are going to include your base plate, your tow bar, a braking system, as well as safety cables.Our base plate is going to provide us with a solid connection point for our tow bar to attach to. The tow bar is going to come from our base plate and that's going to connect to our motor home. Our safety cables are going to go from our motor home to our base plate and these are going to be there as a secondary device or backup.

If a catastrophic disconnect does happen, this'll still keep our Jeep connected to our motor home. And the wiring; that's going to transfer all of the motor home's lighting signals from the back of the motor home to the back of our Jeep.Now as far as the installation goes, it does more or less just plug into our factory wiring, so it is going to be relatively straight forward and shouldn't take you a whole lot of time. Speaking of which, let's go ahead and hook it up together now. To begin our install, we're going to be here at the back of the Jeep. We're going to need to remove our tail lights.

To get our tail lights out, we're going to have two screws here on the inside of the light and so I'll take those out using a Phillips screwdriver. You can see we have the screws out, we can grab our tail light, work it around and pull it out.Now at this point we can disconnect our wiring from the tail light. We're going to have a tab here in the center, push down on it, and then you're able to separate the two. I'll set the tail light aside and then repeat that same process to get the passenger side removed. Now what we're going to do is take our new wiring, we're going to take the end here that has this four pole flat on it as well as the T connector with the orange and green wiring.

There's going to be an opening at the bottom of our tail light pocket down there. That'll allow us to drop it down to the bottom side of our Jeep. We'll take all those, fish it down through there. Then just grab that and work all that wiring down through here.Now with all of that wiring dropped down to the bottom side of our Jeep, we can plug in our T connector here that has the red and blue and the yellow and brown wires. Now our Jeep has some trailer wiring ran already, so there's a T connector in place. This would work the exact same way if this T connector wasn't here and you just had your factory light connector. What we're going to do is take our T connector and just plug it right into this one. Before we do that, we'll take some of the included dielectric grease and just smear it over the terminals. That'll just help prevent any corrosion or anything like that.Now what I'm going to do is just use a couple of the included zip ties and wrap it around our box and we're going to be able to find a piece of metal inside of the tail light pocket that we can secure it to. I'll go ahead and do that now and then I'll show you what it looks like. This is what the box looks like once I have it secured. At this point we can take our tail light and apply some of that dielectric grease to the connector and simply just plug it in to the other end of our T connector. Now with everything plugged in, we can just re-install our tail light the same way that we removed it.Now here underneath our Jeep, I went ahead and routed our green and orange T connector wiring over to the passenger side. Here's the path I took: it dropped down and I ran it back through here along our hitch and I tried to stay as far away from our exhaust as possible and I just used some zip ties to secure it. I ran it up along through here and here's where it comes and drops down. Now before we can put this into the passenger side tail light pocket, we're going to have a panel that we need to pop off. And that panel is going to be located right here.What I'm going to do is just take a pry bar or you can even use a larger screwdriver and push that panel up. Now whenever we push this up, there is going to be a little bit of insulation on top of it. So we're going to pop this up out of the way and clear out enough space for us to push our T connector wiring through. And in our case it looks like we don't have any insulation. Some Jeeps do, some don't. So if yours does have some insulation foam right here, like I said, you just move it out of the way and off to be able to push your T connector through.Here's where our wiring comes up into the tail light pocket. What I went ahead and did was take that panel that we popped off and drilled a hole on it. That way we can slide it and inaudible 00:07:20 wiring and you can work it in there and simply just pop it back in place.Now I went ahead and sealed up our hole there using some butyl tape. Now if you don't have that butyl tape, you can always use some silicone or anything like that too. What I did was just zip tie up our extra wiring just so it's not dangling down and getting in the way. At this point we can take our factory plug, before we plug it in, go ahead and put some more of that dielectric grease on and just snap the two together. Then at that point you can go ahead, grab our tail light, get it greased up and connect it. Once it's connected then we can go ahead and reinstall this tail light as well.I went ahead and ran our four pole flat wiring to the front of our Jeep and this is the path that I took. It's all on top of our frame rail and I ran it forward and up and over this mount here where our shock and our spring goes. And it actually drops out right over it here by this tubing. Now when you route your wiring you want to make to avoid any hot or moving parts as best you can and secure it really well using some zip ties. It dropped down along some brake lines and then about right here I actually ran it over our frame rail to the outside of the frame and followed it up to the front.Here's where it comes over our frame to the outside of it, just around this body mount along through here. Our Jeep has some running boards, so I just ran it through those brackets. And just up and along and again around this body mount. What I did was just peel our wheel aligner back a little bit and I was able to run our wiring up into the engine compartment. There's where our wiring comes up the firewall and I just secured it to some wires up here to keep it nice and tight. Then I just ran it underneath some of our factory wiring and I had some extra so I just balled it up and secured it here under the hood. Up along and now this actually drops down through an opening here, that way we can get it to our base plate. On the underside is where it drops down to, then I just followed some wiring up and over. That way we could get it to our base plate here.Now at this point if you happen to be using a four pole style connector, what you would do is just take your white wire here with the pre-attached ring terminal and use an included tech screw to ground it down to the frame. Now chances are pretty good and a much more common setup like we're using today is a six way connector. So what we're going to do to attach our six way connector is just cut our four pole flat connector off. What I'll do is just take a pair of snips and cut the wiring that connects to it.Now with our wiring, what we're going to do is separate them. I'll take a pair of snips and just carefully cut in between. We'll peel this back a little ways, give us some room to work. But what I like to do, just that little spot that we cut, just trim a little bit of that off just in case we cut into the wires. Now that we have some wire to work with, what we're going to do is strip some of that insulation back so we can get ready to plug it into our six way.Now since our six pole still needs to be grounded and we lost our white ground wire whenever we cut off our four way connector here, since it's connected, what I'm going to do is just cut that white ground wire and now we can strip this end back as well. That way we can hook this to our six pole connector. We already have a nice attached ring terminal, so as I said, we'll hook this to our six way connector along with our other three wires. And then we can find a spot to secure this as a ground.What we're going to do is take our little piece of rubber here that acts as a protector for our six way, we're going to run all of our wires through it and then we can work on getting them connected. If you look at the back of our six way, going to have our terminals here and they're actually going to be labeled. The ones that we're going to use are TM and that's for tail lights so our brown wire will go to it. GD, which means ground, so our white wire will go to that. This one here is going to be LT, which means left turn so our yellow wire will go to it. And finally we're going to have an RT, which means right turn for our green wire.The way these hook up is these little set screws will get backed out and then we're just going to take the corresponding wires and plug them in. We'll do the brown, which will go into TM. We'll push that in there, and then just tighten down our set screw. I'm just going to use that same process to get the rest of our wires hooked up. Here's what our wiring is going to look like once it is all hooked up here at the six way. What I like to do is just take some dielectric grease and just put it over the terminals just to help protect them a little bit. Then we can take our cover, push that into place. Now what I'm going to do is just grab a couple of screws and secure this to our base plate. That way we can figure out where we need to run our ground wire. Now to secure our ground wire here, I'm going to put it along this beam here in the backside. I'm just going to use the self tapping screw to get that secured.Now with everything connected it's a good idea to test it to make sure everything is functioning properly. I'm using a tester box, but if you don't have one of these, you could always just hook up to your motor home and do it that way. We'll first start by checking our tail lights, our left turn, our right turn and our brake lights. And that'll finish up our look at and our installation of the Hopkins Custom Tail Light Wiring Kit for Towed Vehicles on our 2010 Jeep Wrangler.
