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 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.Easy plug and play! The factory harness plug is taped up pretty well behind a lot of wires- remove the tape carefully so you don’t cut into any of the hundreds of wires under the dash. Harness length is plenty long enough to tuck the unit near my right knee in a 2003 Tundra. 768410
The wiring package worked fine for my 2013 Land Cruiser. Previous pictures posted by others were very helpful in identifying the appropriate plug to release behind the switch panel. As stated, it is in a holder, but otherwise easily freed with a small tab on the bottom of the fixture. Further, I was able to locate the Tekonsha controller on the passenger side of the steering column, over my leg operating the accelerator. The space is tight, but sufficient. As another stated, I don't care for the lack of an off button, but it does go to sleep, extinguishing the light. My contribution is that the removal of the switch panel to start the whole operation goes as follows: 1) Using a thin plastic putty knife or equivalent, pry the panel trim at the lower left side first. Take time to safeguard the easily damaged plastic. The first tab came off easily for me. 2) Work upwards on the left side to the top left of the panel. There are tabs at each corner that have a mild spring action to fit and need only gentle pressure. The top trim panel tabs need to go down a bit to release. 3) Coax the third (right top) and fourth (fight bottom) tabs out, taking special note that the entire trim piece is not only secured by the four corner tabs, but a lip engagement where the trim fits under the dash trim immediately to the right of the trim. 4) You may need to lift the trim just to the right of the switch panel to extricate the switch assembly. It is secured by a tab at the top left. Note that the air bag contained behind this trim piece is not compromised by any of these actions. 5) You should now be able to remove the switch panel, albeit with some wriggling. 6) The wiring is long enough to route to the spot I noted, and the ground wire secured at a point to the left and below the assembly that originally held the factory controller plug. It takes a 10 mm wrench and can be easily used as a ground. I did release the trim to the right of the switch trim, and it helped to route the wiring. It powered up but I have not used it yet, so this note is only to help the other Land Cruiser person out there remove the switch trim without a reciprocating saw. 388423
KRT - 06/06/2018We 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. 99168

Tekonsha brake controller plug-in wire worked awesome. Clicked right into my 2012 Toyota Tundra and straight into my Tekonsha P3 brake controller. Zip tied excess wire below dash and installation was complete. Recommend this to everyone. 566110
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. 210331
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. 11353
I am now much more confident driving a trailer with the installed: Tekonsha Plug-In Wiring Adapter. Given advice to get a brake controller for hauling a heavy load such as a travel trailer, I decided on the Tekonsha. I located the controller in a place that was mostly out of the way, and the connection was relatively easy due to the vehicle having a connection for such a device. So, after installing it, I really noticed the braking with the trailer was much easier, and I felt much better about emergency situations since then. Since purchasing the controller I have gotten a lighter trailer, and the brakes really grabbed. After adjusting the level of braking using the controller, which was very easy manual button pushing, the new trailer's brakes are now controlled while I brake. It's an awesome unit. I suggest anyone hauling a trailer to get this particular unit. 643911
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. 115202
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.

Extremely fast delivery as advertised good solid products 831623
Great product. It does exactly what Tekonsha and etrailer say it will do. Also, as opposed to many retailers out there, which ask for a report a couple of days after you got the product, etrailer waited one year to ask for my opinion An honest approach. 831493

Great device to adapt my factory harness to the brake controller! Fits perfectly and the trailer stops so well I don't even feel it "pushing" my truck. 822447
