If your vehicle already has a 4-way flat, this kit includes everything you need to install an electric trailer brake controller and 7-way connector. If there's not an existing 4-way flat on your vehicle, you can purchase one separately.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.
Jon G - 05/08/2021I 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.
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.
Purchased a Teckonsha Voyager brake controller and the ETBC7 install kit. The instruction an video were very clear and easy to follow. Installed on a 2007 Ford Ranger Sport. Tech support was also very helpful on the one question I did have.
David - 11/08/2020I 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...
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.
Steve C - 05/21/2020I 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!
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 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.
David - 02/02/2021The 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.
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!!!!
matt - 03/05/2015Worked perfect and had plenty of wire to run from rear to engine on quad cab short bed. I used a bunch of extra zip ties because what came with it wasn't enough.
Jason - 04/09/2021Yeah my trailer wiring kit from etrailer for our 2008 Ford Escape worked out great...followed the enclosed instructions and watched the video on the site and installation was a breeze.Good quality components and great customer service make etrailer my go to for all of my towing and transport needs.
Everything is good, except for the 7-pole receiver. It is too shallow and doesn't hold the trailer-side 7-pole connector, which slips out under its own weight. So now I have to hold it all in place with a zip tie (which I cut and replace with every use...ugh. Maybe I'll glue a velcro strip on or something. If the receiver was deeper and the spring and catch on the receiver cover flap were stronger, this would be a great improvement.
Henning G - 09/08/2020Company is fantastic to work with in every way. The universal install kit is good and comes with clear instructions. The hot wire between the battery and rear bumper was just touch short for our setup and ended up adding some wire in order to mount everything properly under the hood. A year later everything continues to work well.
Very good, however fitted to a Subaru Crosstrek - not an easy job because you cannot get to the brake pedal switch connections. However made a "work-a-round". Used Curt tow hitch, this wiring harness and Tekonsha Primus brake controller. Works very well.
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!
I have completed the install of the ETBC7 along with the Tekonsha Primus IQ brake controller on my 2019 Ford Escape with tow package. First I must thank etrailer for the multiple instructions and videos that made this job something I was able to do. I saved about $400 as compared to the local RV facility and I dare say my job was better. First I was able to take the time to carefully routed everything and determine the best paths. I also was able to add zip ties and split loom to really tidy up the job. While it took me much longer than the 3 1/2 hours they quoted, I was happy to be able to do it. The video of the gentleman doing the install on the 2017 Escape was tremendously helpful. From wire routing to the indication of the plug on the firewall beneath the fiber matting, it was good. Here are some tips I can offer at this point. I was unable to get a fish of any sort up from the bottom of the vehicle as the video showed. However, another site shown someone putting the duplex wire up though the inside fender. This turned out to be a very good path. I was able to use a piece of 14-2 [wire] as a fish and bend it to make it easy. I was able to use a piece of 1/4 inch poly water line as a feed through the firewall to access the cabin. It just kind of bunched up by the battery and I was able to hook it out. The attachment of the signal wire to the cold brake wire was the most difficult task as the area is very tight. My right elbow is quite bruised as a matter of fact from all the pressure and torque it received as I worked in this tough environment. I had just about given up hope of getting the supplied inline splice in place and closed. I highly suggest a path that I figured out. I went and got a T-tap splice (see pic on wire before male tab was inserted) which made it relatively simple to attach to the signal wire as you are only doing one interface at a time then. Then put a female QC on the red brake controller wire and plug it in, I was able to remove it later when I changed my mind about the underdash wiring. Very convenient. Also I am not a big fan of exposed hot connections right under the hood. I added some bolt covers, (vinyl caps I happened to have) (see pic) to the circuit breakers to provide some protection from shorts by metal objects. etrailer, the addition of some covers to the circuit breakers bolts would be inexpensive and the inclusion of a T-tap would also make a better kit. Thanks
Absolutely perfect kit for my G3500 Chevy van. Unfortunately these vans don't come pre-wired for trailer brake kits, so we have to add our own. The instructional videos on the website are excellent and give all the information needed for install. Thank you so much for a great product! I have been using it one year now pulling our travel trailer, and it has been flawless.
The brake controller and 7 pin x 4 pin receptacle were received promptly and in good condition. The quality of the parts was very good. The instructions were a little confusing. The receptacles had their own instruction sheet and the brake controller had its own instruction sheetand they kept referring and deferring to each other. Way too many instruction sheets. The most helpful was the color coded wiring diagram and the white instruction sheet printed on both sides. It was definitive and guided me step by step for each wire. The installation was not difficult, but it was time consuming. I thought it would take 3-4 hours, but it took me 8 hours. That's because I didn't want to do a halfway job that would fail after I ran through a couple of mud puddles. I used stainless screws and nuts for the hitch receptacles and I soldered most of the connections under the dash and the hood. When I finished the job, I turned on the ignition and got an "nc" reading (not connected) on the brake controller display because I did not have a trailer hooked up yet. When I turned off the ignition, the display remained lighted with two dots showing. I was concerned that since the brake controller and the 7 pin receptacle are both connected directly to the positive post of the battery, I would drain the battery since the controller display did not go dark when the ignition was turned off. Apparently, there is a 15 minute delay before it turns itself off which I read somewhere on one of the many instruction sheets. I would suggest that E trailer or the mfr put a statement at the end of the installation instructions explaining that the controller display will shut off after X minutes to prevent draining the battery. I am happy with the units, the price and the delivery and would recommend it to other DIY mechanics.
Eric C - 10/15/2020 Eric C - 10/15/2020Installed the ETBC7 kit on my 2002 Dodge Ram 1500 Quad Cab. Went just fine, with plenty of extra wire included. It has performed very well. Don't stress over routing the cable from back to front, it lays in very easily. Sure have enjoyed knowing the electric brakes are back there. Heartily recommend this kit.
Landon T - 01/01/2021My truck was stolen and wrecked. I had to reinstall the Tekonsha brake controller in my new truck using this harness. I did not have any problems with the installation at all. Thank you eTrailer for the great support.
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.
The installation turned out well. Everything you need for a professional looking install is included in this package. We plan to tow a Little Guy mini max trailer with a 2017 Toyota Highlander which has a tow package but it only had a 4 pole trailer harness so we needed to upgrade to a 7 pole. A friend helped me with the install which only took a few hours.
