I purchased this 7-pin connector for my 2007 FJ Cruiser. I was excited to get this installed, and found that the wiring was solid. I chose to cut the 4-pin connectors off of my FJ and this adapter. The fewer plugs the better! I like to solder and shrink wrap me connections. While the plug and wiring are really nice, the mounting bracket is junk. It’s very thin metal which appears to be simply painted, not powder coated. It also has a notch on the side for the 4-pin connector. This is the worst part. The rubber around the 4-pin is grooved, presumably to fit into the notch in the mounting plate. But it is not secure at all. The 4-pin simply falls out and dangles even with nothing connected. And there is no way to secure it. This is a significant design flaw.


Comments
Thank you for your review! It actually looks like you have that bracket on the wrong side of the 7-Way. The right side is a little wider so if you flip it to the left side youll have enough room for the 4-Way to fit properly.

1 year review. I installed this product on my 2017 Toyota Highlander. As a person inexperienced with vehicle electrical systems, I found the installation challenging but achievable. I appreciated the advice and videos from etrailer.com. I liked the final fit and finish on my vehicle when using manufacturer hitch and bumper kit. After 1 year of usage, I have found 4 specific opportunities for improvement. 1. Water accumulation in the plug cover flap. After rain, I flip the flap up and water spills out of the crevice in the flap. There is also a small amount of water in the plug itself, but unclear if there is rain entering the socket or if this is from spillage when the flap is opened. This needs to be sealed to protect the plug! 2. Poor quality top mounting nuts and bolts. I overtightened one of the top bolts and it sheered off. I replaced it with zinc plated hardware. In my picture you can see after 1 year of use the included bolt on the left is corroded and the hardware store bolt looks new. 3. Poor quality front mounting screws. You can see the 4 rusting screws in the picture. These are designed to be exposed to weather, so I was surprised to find rust forming after the first few weeks. 4. Poor quality attachment point for the flat connector. The 4 way slips onto the side of the 7 way mount and is held on by rubber friction. It never stays in place and is always dangling. One other suggestion is to offer a kit made for the newer wireless brake controllers. It could have less wire, fewer connectors, and cost less. Because of the above problems I will have to replace the 7 way plug soon. Therefore I gave the product only 2 stars and would not recommend purchasing it.

The installation videos and instructions provided by etrailer are exceptional and are one of the main reasons why I purchased this kit. My second reason for purchasing this kit rather than buying everything local was for the duplex wire which I could not find local unless I was willing to use outlet wiring or two single wires. There are two things I don't like about this kit and two things that just bothers me. First the duplex wire I wanted so bad is too short. I had to mount my controller on the left side of steering wheel just to have enough wiring. Second the wiring on the 7/4 way connector isn't even a foot long so I had to remove the large ring terminal carefully and install it on a piece of white white I cut from running the duplex from the back to the front and use a buck connector to join it to the white wire on the 7/4 way connector. Once I did that I was finally able to ground the connector to my frame. As well I don't like how the 4 pole connector can easily fall off the bracket. It makes the connector look cheap. Lastly, they should really include the No-Drill Mount 18140 with the kit. Thankfully I was able to use my old mount for my existing 4 pole. So if the duplex wire had been two feet longer and the kit included a better 7/4 way connector I would give this a 5 Star rating.

I have a 2018 BMW X2 that did not come with a factory tow package. I had an etrailer hitch and 4 way plug installed last year and has been perfect since. I just recently purchased a camper and needed to have a Brake controller & Brake controller 7 way deluxe kit installed. My mechanic installed them with the detailed instructions that the units came with without any issues. The Tekonsha P3 is extremely user friendly and is working flawlessly. A bit overkill for my car being I can only tow max 3500 pounds, and my camper is 1 axel. this unit is rated up to 3 axles. I look at it like this way, when I trade in my BMW I will take my P3 with me. etrailer is amazing with the support & products they provide and I highly recommend them to anyone who asks me.

Included everything needed to wire the control unit for the electric brakes on my sailboat trailer. Installation of the 4-wire flat plug & the 7-pole plug was a snap. The hardest part of the whole installation was running the wire from the plug at the back of my 2015 Subaru Outback to the engine compartment, because I chose not to just run it outside underneath the car, but rather inside along the floor/ door jambs driver side; but it was very do-able and made for a very 'clean' install. Subarus have a factory installed plug to connect a 4-wire flat trailer plug (easy), but nothing for a 7-pole plug as they are not normally used to tow a trailer large enough to use electric brakes. However, the brakes on my trailer had been converted from hydraulic to electric by the previous owner. The Subaru brake switch has 5 wires coming out of it, so I had to go to the dealer and ask them to identify the specific wire I needed for the brake control to be correctly wired. Done, done, & done. :-{D

Very straightforward install on our Jeep JKU. Plenty of wire and everything you need for the job. Only dropped it down to 4 stars for 2 reasons: First the provided screws to attach the bracket to the chassis are garbage. Both snapped off in the holes and had to be drilled out adding quite a lot of time and swearing to an otherwise easy job. Secondly the bracket attachment for the 4 pin plug is laughably bad. It is so loose that I am sure it will spend most of its life dangling after it falls off.

Great product. Everything I needed was in the kit and instructions were great. The kit was installed in a 2019 Highlander. The Highlander came with a 4 pin trailer hookup and we needed the 7 pin to include trailer brakes and a charge line. Works great!! We are towing an Rpod trailer with trailer brakes.

Overall, this is a good kit, and is much better than having to do it from scratch. I mounted this on a 2016 Chevy Express 2500 with a DrawTite class V hitch. This kit did not come with an L-bracket to mount the receptacle to a hitch like they show in the video. But, you can get one from etrailer. I fabricated my own L-bracket and mounted it upside down so it would be protected from road debris by the hitch itself. It made the receptacle fit perfectly against the bottom of the bumper. (see pic) You will also need a couple extra blue butt connectors for this particular vehicle that are not included in the kit. It would also be nice if the kit came with a few more feet of wire covering to use under the hood. I would recommend following the video carefully when installing the Tekonsha Prodigy 2 controller. It's a great video.

Product still works great.

I will be using this kit along with echo wireless brake controller. (No wire running to cabin!!) however, the 10 gauge wire was very slightly too short from perfect spacing for my 2017 highlander( doesn’t have room for make any loop wires for any repair in the future), I terminated the wires at 7 pin connector and then routed the wire under body, it’s dirty and sandy. The terminal lug for the ground wire fell off, but i just re-terminated it and it’s no big deal. I had to loosen some panels and make sure the wire won’t chaff against any structure. I do find that routing the wire down between the fuel tank and suspension bracket could be problematic down the road, but there wasn’t much option. i end up putting some chafe protection foam on the tank and the wires... and aluminum tape the wire to the fuel tank to prevent the wire from chafing against the bracket. Used a lot more tie wrap then what was provided...

Thanks to a tutorial video supplied by etrailer, installing this on my 2017 Ford Escape was very do-able. It wasn't a quick job but the video helped a lot as the instructions are not vehicle specific and will leave a lot of questions marks on where to put the wires. The cabling and connectors were solid, though a roll of electrical tape or shrink tubing would have been a nice addition, as it was used in the tutorial and you should definitely use one or the other on this installation. Cons: THE WIRES ARE TOO SHORT. The ground cable coming from the plug to the chassis was too short to even go straight up the body of my car, a small SUV, much less to a suitable location. I had to cut a foot of the white side of the duplex wire and splice with with a connector. By the way, the tutorial video shows a much longer ground wire, so either they have shortened the cables since the video was made or they modified it before filming. The wires also come in different colors than both what was shown in the video and what is displayed in the instructions for the kit. In part due to having to use some of the duplex wire for the ground, I ran out, though I don't think it would have been enough for what was recommended in the video anyway. In my opinion it would be better to give a few extra feet then a few too few, even if they have to raise the price a few dollars. 4 PIN SLOT: The slot for the new 4 pin connector on the side of the bracket is open on one side. Ordinarily this wouldn't be a big deal if the slot had teeth or the rubber bumper on the plug had a tight gap to fit into and grip the slot. Neither of these are the case and the plug falls out pretty easily. I will need to tape it, or glue it in. RUST? After a week or two both bottom screws on the 7 pin plug are brown with rust? I don't need to explain why that's ridiculous. These cons counter some of the solid pros but if you have the tools and extra products on hand to get around them, this can still be a good choice, especially given the excellent tutorial that is provided.

Everything you need to install a brake controller on a vehicle without a "tow package". In my case I used it on a 2013 Ford Explorer. Because I have an after-market receiver, I had to make a bracket to mount the bracket that comes in the kit to the receiver, otherwise all the necessary parts are in the kit.

product was excellent and COMPLETE. everything you need with very DETAILED directions. i also ordered the prodigy P2 to complete my install. both were excellent and very recommended. only modification was on the actual plastic cover on bumper, i cut away minimal pieces with razor knife for perfect fit. you can look at all the pics to check out install. I took advantage of the reverse light wire and put LED light bar on back of trailer. i made one email to e trailer for exact numbers for my make and model. the response was pretty impressive. Full detail with pictures and product numbers all set up so all i had to do was press order and pay for it. This is how american companies are supposed to be ran......I LOVE IT!!!!

Did the job. No complaints. Everything in order and all necessary cable ties etc. I was connecting to a 7 point connector and therefore fed it through the body (already a hole for cables that can be used) under the vehicle as opposed to only hanging through the closed back hatch per one of the videos.

I used this kit to install a 7 pin connector to my new 2020 Hyundai Palisade. Everything I needed and more was included in the kit. I am using the Curt Echo Mobile brake controller to avoid having to do interior installation work. I had factory installed four pin lights wiring already, which plugged into the 7 pin connector wiring. I only had to run the plus 12V wire from the battery, through a circuit breaker to the 7 pin connector and I connected the ground wire at the under hood ground point near the battery, as there is no solid steel area near the 7 pin connector to connect a closer ground.

I installed this on a 1996 Chevy Tahoe to tow a Coleman camper and car carrier. The installation takes some time to run and connect all of the wires but this kit made it as easy as this kind of job can be. Most of what I needed was in the kit and the instructions were great. Once the wires were run connecting everything up was pretty easy. I do have a couple of suggestions to make this kit better. The length of the cables was ultimately too short to use as required. I ran out of line when needing to run the final section to the positive terminal and brake light switch so the cable could stand to be about 2-3 feet longer. I also had to order and splice in extension lines for my application to be able to mount it to the chassis. Also few more courtesy butt connectors and self-tapping screws would also be good. Overall the kit was extremely solid and video instructions are invaluable. Thanks, etrailer!

Just as etrailer stated, these were the right parts for my 2017 Ford Expedition. I was especially pleased with the easy to follow instructions. Installation took me about an hour, and I'm not particularly handy.

This product could really benefit from stainless screws, lock washers and nuts. I’ve already replaced them due to rust. Could be very difficult to remove if left on for any length of time. Everything else is great.



- ETBC7
by:

I love your videos, which I watch a lot of! Very helpful. I couldn't fit the 7 pin plug to the bumper without extending it somehow. So, I grabbed an Octagon shaped electrical cover and bent that to even out the plug to the ground. I'll paint it black when I'm done with the wiring. I've run the duplex up to the front and today I will make all the connections. Also bought a pigtail for the brake controller.

This is a great product. I think etrailer made it easy for our novice DIY. I basically read the instructions and watched video a few times before I start. The installation is not difficult; it is just a dirty and tiring work. One thing I should mention, is that grounding is very important. I wasted most of my time for not properly grounding. The first place you encounter the issue of grounding will be when you test the break wire in the box under the dash to the left side of the steering column. Using the tester, you must find a bare metal part for grounding, otherwise the other end of the tester would lit up properly. This is not mentioned or emphasized in the video or written instructions. Painted surface won't do since it insulates the metal. I spent a lot of time trying to figure out why the break wire won't lit up, calling etrailer customer service representatives, nobody really told me this. I basically figured out by myself. Hopefully you won't need to waste time on this. The second place you will encounter grounding is in the front engine box near the battery where you must drill into the frame to attach the ground wire, like instructed by etrailer. But I didn't like to drill "unnecessary" holes into my frame, I just used a ziptie to attach the ground wire to the frame, so grounding wasn't good. I eventually figure out I must drill into the frame to get to the bare metal for grounding. The 3rd place is in the back, there is another ground wire you must drill into the frame to reach bare metal. I choose to drill into the tire tub, since it won't affect the structure integrity of the frame rails. Either way it will work as long as you drill into the bare metal. The wires supplied by etrailer is long enough for this installation.

Just upgraded to a 2016 Odyssey and need to tow my camper. Purchased the OEM hitch and OEM custom harness (from car to 4 pin on hitch. OEM Hitch comes with nice beefy flange where the 4 pin connector mounts. But I needed a 7 pin for electric brakes and bought this ETBC7 kit to do the job. I ended up cutting a custom hole in the bumper cover and figuring a way to mount the bracket in this kit directly to the OEM hitch. Wanted to share photos of the install for anyone else in the same boat. Advantage of my install is that the 7 pin is mounted above the bracket, protecting it from injury from low clearance obstacles on the road. One Con, is I had to mount it upside down so it didn't interfere with the metal bumper under the bumper cover. One issue I remember is that the Ground wire on the 7 pin harness didn't come close to reaching an available frame member, at the side of the car. I had to cut off the ring lug and extend it out to the edge of the car to complete the install. But it is done now!



- ETBC7
by:

The etrailer video I watched of this product showed the reverse light wire left disconnected. I connected mine. I also bought some extra convoluted tubing for under the hood, and some expandable braid sleeving for under the dash, and added a connector near the kick panel for connecting to the brake controller. To mount the brake controller, I removed the storage tray next to the ignition switch. Shimming the brake controller bracket allows it to fit nicely there (2007 Tacoma). Under the hood, I used the 20 amp breaker. The 20 amp breaker is for 1 and 2 axle brakes, and the 30 amp is for 3 and 4 axle brakes. I wanted to find some rubber insulator boots for the breaker terminals since theses are hot all the time, but I had to use electrical tape and shrink sleeving. Level of difficulty was moderate. I was very pleased with the results.



- ETBC7
by:

This is a very nice kit. The instructions are pretty good, but the install videos by etrailer are quite good! Almost everything needed was supplied, the only things that I needed more of were zip ties as well as needing about 10 extra feet of the same gauge wire. The supplied coil of duplex wire wasn't quite long enough to make all the connections that the wiring diagram calls out after routing it from the back to the front of my 1994 f150. Everything is easy to install and hook up.


Comments
Everything is still working well. I live in Wisconsin, so theres a lot of salt and other grime on the roads for a lot of the year. But everything is still working as it should whenever I hook up. I do spray a little dielectric grease on the spades every couple weeks or so to make sure they stay clean. All in all, everything is working great!

  • What Is Needed To Tow a Trailer With Brakes With a 2002 Chevy Express Van
    In order to tow a trailer with brakes using a 2002 Chevrolet Express Van you really only need two things, a trailer wiring harness like the Universal 4 to 7 and 4-Way Adapter part # ETBC7 and a brake controller like the Draw-Tite I-Command Trailer Brake Controller part # 5535 which are my recommendations. The install process is pretty straight forward. I have attached an install video I did on an earlier model below which will be pretty much the same as the 2002. Please note, you can...

  • Brake Controller Installation 2017 Nissan Rogue
    You're looking for a light green wire, exiting terminal # 2 of the stoplight switch connector. Tekonsha also recommends using the # 7865 pigtail on your vehicle, rather than the one included with the controller. The pigtail has a diode in it to prevent anything from feeding back into the vehicle.

  • Do Both Wires on ETBC7 Need to be Installed on 2018 Jeep Compass if Trailer Doesn't Have Brakes
    You are correct. If you don't have brakes on your trailer then you can just use the Universal Wiring Kit # ETBC7 as an adapter and then only connect the 12V power to the battery on your 2018 Jeep Compass to help maintain your battery level. I do recommend routing the brake controller wire from the 7-Way at least up to the engine compartment though since this is duplex wiring. This will make it easier to install a brake controller if you need to do so in the future. To keep your trailer...

  • Parts Needed to Convert 4-Way of 2007 Ford E-350 to 7-Way and Install Brake Controller
    Since you have a 4-way on your 2007 Ford E-350 you would need to convert the 4-way to a 7-way so that you can install the brake controller. For that you will want the Brake Controller Install Kit and 7-Way Adapter part # ETBC7. I attached installation instructions and an install video for this product as well. For a brake controller I would recommend the Draw Tite iCommand # 5535. This is one of our best selling brake controller because of how well it works and how easy it is to setup.

  • 7-Way and Brake Controller Kit for 2017 Chevy Express 3500
    The kit you mentioned is essentially a t-one style 4-way kit with a 4-way to 7-way kit like the # ETBC7 so to replicate that you'd just want the # 55540 with the # ETBC7 and a brake controller of your choice like the # 5535 and you'd be set.

  • How to Install Prodigy P3 on a 2015 Dodge Durango Without Tow Package
    That is a bit confusing as to why Dodge would have the plug installed on your 2015 Durango for the Adapter # 3045-P if your model didn't come with the tow package. Since it didn't come with the tow package you need to hardwire everything. Basically just plug the Universal Wiring Kit # ETBC7 into your Curt T-Connector 56198 (replaced by part # C56336) and then route the wiring to your battery and cab for your Tekonsha Prodigy P3 # 90195 brake controller. Unless Dodge has already run the...

  • Recommended Solution to Add 7 Way Trailer Wiring Harness to 2013 Toyota Highlander
    In order to add a 7 way wiring harness to your 2013 Toyota Highlander you'll want to use the # ETBC7 (if your brake controller is wired) or the # ETBC7L (if you're using a wireless brake controller); the difference will be that with a wireless brake controller you won't need to run the brake controller output line into the cab of the vehicle. If you haven't already chosen a brake controller I do recommend going the wireless route because of the ease of installation; I recommend using...

  • Recommended 7-Way Connector And Trailer Brake Controller For 2001 Dodge Ram Pickup
    The Draw-Tite Max-E-Loader Trailer Hitch Receiver # 41536 you were looking at is a great choice for your 2001 Dodge Ram Quad SLT to tow your car trailer. To add a 7-way connector to your Ram you will need to first install a 4-way connector if you do not already have one. I recommend the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118329 as it is a plug and play installation and will not require any splicing into your factory wiring. With a 4-way connector installed...

  • Brake Controller and 7-Way Connector Installation in 2000 Chevrolet K2500
    In order to install a brake controller and 7-way trailer connector in your 2000 Chevrolet K2500 pickup you will first need to have a working 4-pole flat trailer connector and wiring harness in place, such as the TowReady Custom Fit Harness # 118315, which plugs in along the driver's-side frame rail. This 4-pole provides basic lighting functions (stop, turn and tail lights) for your trailer. Next you will need an electric trailer brake install kit, part # ETBC7, which includes the 7-way...

  • How to Determine Stop Light Switch for Brake Controller Install on 2018 Toyota Highlander
    When installing a brake controller, the only way to determine the cold side of the stop light switch on any vehicle, including your 2018 Toyota Highlander, is to use a circuit tester such as the very handy Cordless Circuit Tester # PTW2979 and find the wire that only has voltage when you press the brake pedal. If you take a look at the linked video we did installing the Tekonsha Prodigy P3 Trailer Brake Controller # 90195 with the Pigtail Wiring Harness # 7865 on a 2018 Toyota Highlander,...

  • Parts Needed to Add 7 Way Connector and Brake Controller to 2012 Toyota Highlander
    We can absolutely help you locate the parts you're looking for. Even though you have a factory 4 way trailer connector, you will not have a factory brake controller installation plug available in the cabin of your 2012 Toyota Highlander, so any brake controller that is not wireless would need to be hard wired into the vehicle. For this reason I recommend using the # ETBC7L, which is a 7 way plug designed for use with wireless brake controllers; if you want a wired controller you'll...

  • Recommended 7 Pin Wiring And Brake Controller For 2012 Chevrolet Equinox
    For your 2012 Chevrolet Equinox, I recommend we start with the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 56094. This will simply connect to the factory plugs behind each of your tail lights. It is recommended to use a small amount of dielectric grease like # 11755. If your trailer doesn't have brakes, you will just need a 7 way connector like the Adapter 4 Pole to 7 Pole Vehicle End Trailer Connector # 30717 and a mounting bracket like # 18138. If...

    Yes the brake controller install kit part # ETBC7 is the exact kit you are looking for to convert the 4-way of your 2018 Toyota RAV4 to a 7-way, install a brake controller, and activate the 12 volt accessory circuit for the charge line of your trailer battery.

A no-drill bracket like part # 18140 can be used to easily mount this to your trailer hitch crosstube. After this is done you will use the self-tapping screw to ground the white...

    We have produced many different videos for the # ETBC7 brake controller installation kit. While we do not happen to have one showing your specific 1999 Chevrolet Blazer 2-door rear-wheel-drive version the overall process will be essentially the same on any vehicle. For reference I have linked two videos showing a 2001 Silverado and a 1993 Suburban as examples. I also linked you to an article that covers the complete ETBC7 installation process. Between the two videos and the article...

  • Trouble Locating Cold Side of Stop Light Switch for Brake Controller on 2014 Mercedes-Benz Sprinter
    There are some wires that are hot all of the time which is why we usually try to emphasize that the brake controller, like the Prodigy P3 # 90195, needs to be connected to the cold side of the stop light switch when installing the Kit # ETBC7. Sometimes a vehicle will not have a wire connected to the cold side of the stop light switch which is what you are finding. In that case you will simply need to install the Roadmaster Stop Light Switch Kit # RM-751475. This is typically used for...
