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 vehicle's dash.
Features:
This adapter plugs into the 5-pin connector on your vehicle's built-in brake control wiring harness. The harness is located underneath the dash, to the left of the steering column, taped to another harness near the emergency brake pedal.
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.

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 vehicle's dash.Arrived sooner than I expected. Watched one helpful installation video (not exactly the same vehicle nor same brake controller but still useful). Took me about an hour and half (with heat breaks) to figure it all out and install. Works great. My only regret is that I waited so long to get to it. Saved over $250 compared to RV repair shop installation.
I picked up the redarc brake controller and sumo bags. I installed both today. I have to say I'm excited to use both when I pick up my travel trailer. The Redarc is so clean! It might have taken me an hour to install but that was just bc I was deciding how I wanted to run it . Sumo bags took an hour to out on! I cant tell you how great they work yet. But the install was a breeze.
It would be easy to have this part order and install on the Tundra. i went one step further and end up using the wiring in the box with P3 Trailer brake and had to splice the wiring to make longer extension in order to install the P3 in the empty slot between the lighter and 12v socket which make is more customized look and out of way. Would be cool if they offer longer version for someone who want to install it somewhere else behind the driver's spot zone.
gregory a - 08/09/2017Purchased brake controller for my 2014 Tuna. excellent order/shipping/receiving time.Received everything I needed with order in a very timely fashion. Website made it very easy to find and decide on exactly what I wanted. Etrailer will be my first choice for finding the accessories I need in the future. Purchased Tekonsha P3 brake controller and is the best thing to a factory installed controller I have encountered.
Henr L - 12/28/2017This was an easy plug n play device to allow the Tekonsha brake system be hooked into our Toyota Tundra. We've been using the Tundra with a dump trailer for the past 3 days and the brake system purchased from worked well, as it has for the past year.
Pictures of the install. Approximately a 20 min job. First picture my finger is pointing to the factory plug with the etrailer supplied harness plugged in. Note the harness did not specify that the white common with the ring terminal should be connected to ground. But then again that SHOULD be obvious. I will be towing this weekend so I will rate the product then. One minor gripe is that there is always power to the unit which is a battery drain (as evidenced with the key out of the ignition and the unit stayed on) Not sure as to the impact but the controller can always be unplugged or removed. Sorry for the dirty floor mats in the photos.
Patrick B - 01/30/2014For this harness you can either run the ground to the negative side of the battery, or use a know ground location within the vehicle. Running the ground to the negative side of the battery will yield a better connection, however you may have to extend the wire to reach the battery. Either way you choose to ground the controller it is always recommend to test the brake controller at slow speeds and make sure that it is functioning properly before starting a long trip.
-- Rachael H - 7/1/2014I used the adapter to attach to harness that was supplied be Etrailer. My truck wasn’t wired for a brake controller.
Good product. After I finally found the plug on my 2012 Toyota Tacoma I had no problems with this connection cable at all!
T. K - 04/10/2021We ordered a part for the 2008 Land Cruiser and was told that it's the same installation. IT IS NOT! The connection to the harness is not in the same location as Tacoma. After looking for more than an hour, I got smart and found some info on another website. Even the manufacture has the info wrong. So, if you have a 200 series Land Cruiser, your plug is located under the dash behind the switches for the mirror. You will need to take apart the lower dash panel and then push out the switch panel. There is no need to detach any switch, it all hangs out just fine. See photos for the location of the plug. Plug the adapter in from there you can follow the instructions.
Patrick B - 09/10/2013Easy plug and play installation on my 2003 Toyota Sequoia with the factory tow option (maybe the tow package is standard equip, I purchased the vehicle used). My 03 Sequoia is 2WD and has a frame mounted hitch receiver, 7 way round trailer wiring connector and a transmission cooler. The factory harness is behind the left front kick panel. Remove the drivers door sill trim and one plastic nut on the cover. Factory pigtail is capped and taped. The controller harness could have been a bit longer for my setup on the right side of the steering column.
Install is very easy once you locate the vehicle's brake controller plug. The plug in a Tacoma is extremely well hidden. It is high above the driver's side kick panel taped behind a plug wrapped in foam. I have attached a photo to help you locate it in a late model Tacoma. Once I found the plug, the install took less than 20 min. The controller works great.
Mark N - 06/05/2015Installed P3 this weekend in 2013 Tundra Crewmax with towing package and pre-wire. Extremely easy, even with the center console installation. Will let the photos tell the story. Did have to combine the P3 included harness with the additional OEM harness to gain the length I needed. Plug and play with the pre-wire. Hooked up to trailer and set boost levels for varying loads. Works great! Vast improvement over older model Tekonsha controller in my Ram 2500 Diesel. Pull a Kiefer BP horse trailer: about 3600 lbs empty, 7500 with 3 quarter horses and gear. Usually pull 6-8 times per year, with only 1-2 horses. Short distance and flat terrain. It took about an hour to install. Dad is a retired USAF/FAA radar technician with every tool known to man. He QC'd the job. Will try to write better review later.
Great products and quick response, BUT, somehow the Wentzville Post Office sent my order to me via ALASKA, so it was late arriving. I don't think etrailer had anything to do with that! Won't hesitate to order from them again.
I ordered a brake controller with pigtail for Toyota nd it was delivered quickly. After I installed it a couple weeks later I discovered I didn't have a good connection at the controller. I contacted etrailer right away and they promptly sent me a new pigtail which solved the problem. My only complaint is you have to wait a long time before you can get someone on the phone, but maybe that is because of the coronavirus thing.
The cable fit and made the Tekonsha brake controller a very easy installation on my Toyota 4 Runner . Phone order was quick and easy with a very knowledgeable and friendly staff. I have ordered several times here and each time it has been a very good experience. Great prices, Great shipping as well as Great sales staff !! A customer for life , I wish all companies were this great to deal with!!!
Tim B - 09/19/2020Made the installation of the P3 brake controller for my Toyota Tacoma easy. The only problem was caused by Toytoa. The connector from the truck, not the adapter or P3, was tucked up behind other wiring, hard to see if I had not been told to look for it. Easy, easy installation
Easy to install. Owners manual had location of factory plug and we installed the entire system in less than an hour. We used the removable bracket so the unit can be stored in the case that was included with the controller when not towing so it is completely out of the way of the drivers legs and knees. We are a collision repair shop and I would rate the ease of installation as relatively easy if you just use common sense and consider wiring location and controller location BEFORE drilling holes in the plastic lower dash cover. Also need to be mindful on the lower air bag that protects the drivers legs in a serious collision and the routing of the wires if you install it on the right side of the steering wheel. We used wire ties and a small plastic wire holder to place the wiring in a secure place that does not rub through the wire insulation or get snagged by the drivers feet. See the attached photos. All work was performed in slightly less than one hour.
This wiring was exactly as describe , for sure i recommande , will buy again from etrailer
Worked like a charm! Had to remove some of the lower dash to reach the connection, but a video helped with that. Plugged in the pigtail to my brake controller, and viola - brakes, and lights, for my trailer!
MattC - 09/23/2020Worked perfectly on my 2007 Tundra. I had to extend the wires, only because I decided to mount my P3 under the radio. If you were mounting in the normal kick panel location it would work fine as is.
No hassle hookup. etrailer was awesome, they shipped my P3 and this connector immediately and provided great tracking. They also followed up afterward. Excellent customer service!!! Real customer service is hard to find these days. Thanks etrailer!!! I haven't towed my travel trailer yet but the controller is installed in my 2008 Tundra and looks great. Everything seems to be working as it should. I can't wait to try it out. Regards, Dale V.
I bought a new trailer and wanted to go camping. I did not have a brake controller. I called around and to get a Prodigy P2 installed it would be a 2 hour drive to the dealership plus about $200 bucks for parts and another $115 for an hour of labor. I found this website, got the prodigy P3 plus 2 day shipping and installed it with their super simple video in 15 minutes all for less than $200. I was very pleased to say the least. I highly recommend them. Service was outstanding! Video instructions spot on and simple.
Excellent service,product and quick shipping. Plenty of time to install before I pick up my new camper on Monday.
Really simple install! Gor my Tekonsha controller hooked up and ready to go in under 1hr
