Install your electric brake controller quickly and easily with this custom wiring adapter. Simply plug one end of the adapter into your brake controller and then plug the other end into the built-in harness beneath your 's dash.
Features:
This adapter plugs into the 4-pin connector in your vehicle's junction box. The box is located underneath the dash, to the left of the steering column, just above the carpeting.
To install your electric brake controller you need to connect the wiring of the controller to your vehicle. Certain manufacturers offer pre-wired options, typically known as tow packages, wherein these wires are run for you from the dash to the trailer connector on the back of your vehicle. Often, a brake controller wiring harness is included with your tow package. This harness plugs into a port beneath your dash and connects to the four wires of the brake controller. If, however, you have a brake controller with a plug in place of the four loose wires, you can use the Tekonsha adapter.
This adapter requires no hardwiring. It is designed to plug directly into your electric brake controller for the simplest installation possible. Because there are no wires to connect, installation is not permanent. You can unplug and remove your brake controller at any time and securely stow it away.

Does exactly what it is supposed to. The only issue I had was having to run a new "blue" power wire for the controller to apply current to the brakes. It would be nice if one could just plug into a harness and utilize the stock wire in the stock 7-pin connector. 2015 chevy 2500hd
I was in a bit of a spot and needed a trailer braking system in a hurry for my 2018 GMC Sierra pickup. After looking around at all the local automotive shops and part stores in the area... I was at my wit's end as no one that I spoke with had any information as to whether or not the unit they had would work for my truck. So I jumped online as it was getting down to crunch time and I needed the unit as I was to pick up the travel trailer and a couple of days. I went online and found etrailer.com After very little research and a quick phone call to tech support... they knew exactly what I needed along with the adapter cord that plugs right into the fuse panel. It took me all of 10 minutes to install the unit and it works phenomenal. Also due to the amount of time I had to get the unit and get it installed they expedited the shipping and I had it the next day. These folks know exactly what they're doing and what you need and will not disappoint. I have never had an easier and more pleasurable installation of an aftermarket product. I cannot recommend them highly enough. Thank you very much again a very satisfied customer. I purchased the Primus IQ which is a proportional braking system and again it came with a harness that went right into the fuse panel in my truck. The instructions were easy to follow and a unit works very very well. As I said 10 minutes to put it in at the most. Great job guys thanks again.
Steven T - 07/01/2021I had purchased and used the Tekonsha Prodigy P2 Trailer Brake Controller on my 2000 Silverado with good results. When I got a new-to-me 2104 Silverado, I thought I could just buy a new cable and I was correct. It was delivered quickly and plugged in with no issues. The new truck's lower dash panel is more vertical than the older truck and I didn't want to drill holes in it for the mount, so I purchased heavy duty Velcro tape and cut it to fit. It has worked without issues.
GW - 10/25/2018FAST SHIPPING!! Great products!!!, I highly recommend purchasing from etrailer!! Easy to put together and install only takes minutes!! I'm using these products to pull a 30ft travel trailer and it does a GREAT job! Hooking up the distribution bars is so fast and easy they just slide in and your done, and the brake controller automatically sees your trailer and saves your settings, so you don't have anything else to do!!
Luke L - 10/22/2017Recently bought a Tahoe to tow my small camper. It had a tow package but no integrated electric brake controller. I experienced a bit of frustration finding the location of the four-pin plug-in on the vehicle (in the past when I have attempted this project it was always under the dash to the far left). Kaylyn R. was prompt to respond to my message requesting assistance in find the location for the plug and identified the location as in the junction box behind the emergency brake, above the carpet. Still took some head scratching to locate the exact location, but when I did the installation was flawless from there. I now have trailer brakes.
Unparalleled excellence, etrailer’s continued customer support after the sale is why they should be everyone’s go to source for trailer parts and accessories.
Henry - 03/17/2022Excellent product and great service for the purchase. Bought several items from this company and always exceeds expectations. Kit plugged right in to factory socket and works perfectly.
John - 02/12/2022The wiring adapter I ordered was easy to install by following the included instructions! It is vehicle specific ,so I ordered one that fits my 2019 silverado 1500.It plugged into the 4 prong receptacle inside the block box under the dash to the left of the brake pedal against the fire wall.The other end plugged into the brake controller that I ordered(the wire adapter fits several different brands) I installed the Kenosha Primus IQ. Both items had concise, clear instructions with them.After finishing the install I plugged in the travel trailer and set the the brake controller by the instructions and it is working great!The install took me about 20 minutes.
Received the wiring harness and bracket for the brake controller quicker than thought. Though there was a lack of instructions enclosed I found explanations on line on Etrailer site that detailed installation. The only thing missing was though the wiring harness fit, it did not snap into place. Not sure if that is correct or not. Products performed without any complications though. I would recommend these pieces to others.
Installed the Voyager Brake Controller on my 2018 Silverado Custom Truck. Installed quickly and effortlessly with the wiring harness. Simple Plug and Play.
Plug and play easy to install. Hardest part was finding the wire harness plug in the car. I called up and they told me where to find it. It wasn't the usual plug hanging back there it was plugged into a box. Thanks for the help
etrailer always takes excellent care of me! Fast shipping and courteous service. Not my first purchase and won’t be my last!
Received my brake controller and plug in timely manner. Easy to install and seems to work like a champ although have not used it other than a short test drive with the trailer.
Easy, fast shopping and delivery. Quick install with the included instructions and the help of YouTube.
Paul O - 09/17/2021etrailer makes the purchase easy. I have always used Tekonsha Voyagers, and on my new truck (2015 Silverado) I also wanted the convenience of having the plug and play wiring harness. etrailer had exactly what I needed and was very easy to find on the website. Installation was flawless and clean thanks to the good hardware supplied. Very excited to put some trailers behind the truck with the stopping power confidence that comes with the Voyager.
Direct fit. Made installation a breeze!
Clip is designed too loose and trailer brake controller loses connection if plug is wiggled, have to use a zip tie to hold it tight to get a proper connection. Other than that it’s the proper length to keep it from dangling by your feet and has worked ever since adding a zip tie
Best and easiest thing I have bought in a long time. 2014 Silverado. Does great. 10 minute install.
The Tekonsha P3 is an outstanding controller. Highly recommended for anyone wanting a good for a user friendly controller with nice options. It looks great in my 2014 Silverado. Buying from etrailer was awesome. I suggest getting the wiring harness made specifically for your truck as well. Thanks etrailer.
I have bought two of these with no problems, great product and easy set up. Thanks etrailer.
J.Prince - 10/08/2021Recently bought a Tekonsha Voyager Trailer Brake controller along with the wiring adapter (#3016) for my 2014 GMC 1500 pickup...I installed everything myself in no time flat and had no issues whatsoever.....I was impressed at how easy it was to install...Once I got the cover off my trucks electrical box the rest went quickly...Am totally impressed with your company and your products.....I would strongly recommend your company and your products to anyone & everyone.....Well made products and I know I saved a bunch of money being doing this myself in no time at all....Thanks for supplying well made, perfect fitting products....Impressive.....
Tom K - 07/20/2015This cable made it very simple to connect to my Tahoe. I appreciate that they knew which cable I needed so I didn't have to wire it in myself. I wish all web sites made it this simple. The instructions with the pictures made it very easy to follow and it worked first time. GREAT JOB!!!
Wiring harness made it simple to connect - much easier than making your won harness!
I just purchased a new 2017 Chevy Silverado 1500 4.3 L V6, 8ft bed, base model truck, with no options. The truck is rated to tow a 5900 lbs trailer with a CGVW limit of 11000 lbs. I will be towing a Lance 1985 travel trailer, that weighs in around 4500 lbs wet. With excellent reviews and outstanding installation videos from etrailer.com, I ordered the Curt C14006 class IV hitch; the Tekonsha proportional Prodigy P3 brake controller; the Tekonsha plug-in wiring adapter specified for my truck; Cipa custom slip-on towing mirrors; and the 7- and 4-Pole Trailer Connector Socket w/ Mounting Bracket - HM40975 specified for my truck. All new Chevy Silverado 1500's (even the base model with no options) comes from the factory pre-wired with a basic seven wire trailer towing harness already installed. Everything electric just plugged in without a single cut or splice of the wiring or any other wiring modifications. I just followed the instructions in the excellent installation videos on the etrailer.com website. The hitch installed quickly and lined up perfectly with factory bolt holes already on the truck frame, no drilling required. Finally I slipped on the Cipa custom towing mirrors and I was ready to tow after about two hours work. If I would have ordered my truck with a factory tow package, integrated brake controller, and extendable towing mirrors, the options would have run me slightly over $1450 on a new Chevy truck. Instead, I spent two hours of my own time doing the installations and paid about $550 for all the parts by ordering by from etrailer.com. Nice savings. You need to have a good set of socket and open end wrenches, including a torque wrench adjustable to a minimum of 110 ft/lbs for the hitch bolts. Spend some time and review all the installation videos for the parts that you need to order. The etrailer.com website also has downloadable installation instructions provided by the parts manufacturers.
