Installation of Tekonsha Brake Controller Adapter

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.

Video Transcript for Trailer Brake Controller Installation - 2004 Toyota 4Runner

Today on this 2004 Toyota 4Runner we are going to be installing Prodigy brake controller along with the Prodigy wiring harness part number 90185-3040P. The first thing we want to check for in this vehicle just to make sure that the vehicle is fully equipped with the tow package and that it will have the port that we will be plugging into. A good way to check that is to come to the rear of the vehicle and make sure it has a factory installed 7-pole and not just an after market one. With that verified we can go inside the vehicle and start locating the wiring port that we are going to be plugging our brake controller into. 00:31

The port that we are going to be plugging into is located over on the driver side of the vehicle just left of the emergency brake pedal. Just above the plastic molding we can probably access the plug without removing anything however there is a ground wire on our harness that we are going to need to attach to a grounding stud. To access that we are going to need to remove a couple of pieces of molding. We need to remove the kick plate cover and then the full plastic molding over on the driver side. Now that we have got the paneling removed we can take and plug our harness in place. You can see right here is the port that we are going to be plugging our harness into. 01:09

If you follow down the harness you can see we have got a loose white wire that needs to be grounded. I do not see a common grounding stud in here however there are multiple bolts that we can use as attaching points for our ground. I think we are going to use this one right here since it is somewhere close to where our harness is located. We have got the other end of the plug here and that is going to plug into the backside of our Prodigy harness. Next we need to figure out where we want to mount the Prodigy at. It is always a good idea that you mount it in a aerial. It can be easily accessed by hand in case you need to adjust or for even for emergency braking situations. You also do not want to be in a spot where it is going to interfere with your everyday driving. On this particular vehicle unfortunately there is not a whole lot of excess room in the dash area. I think we are going to mount it somewhere right in this area here. When you are mounting the Prodigy it needs to be mounted in a straight line for the braking of the vehicle. It can not be turned to the right or left either way. Note that the Prodigy controller comes with two different mounting brackets. We have got the more traditional bracket that mounts to the Prodigy using two screws on the side which is a little bit smaller but it is a little more permanent as well. We have also got the mounting pocket which is a little bit more bulky but would allow you to easily remove the Prodigy when not in use or if you want to switch it from vehicle to vehicle. 02:34

Instead of having mounting screws on the sides it has got clips to hold the Prodigy in place. Since we are a little short on room in this vehicle we are going to use a smaller mounting bracket for our installation today. We are going to line it up and start drilling out the holes that we are going to use for the mounting. Before drilling the mounting holes you want to make sure that there is nothing behind the dashboard that you may drill in to that may damage the vehicle. When choosing a mounting location you need to take into consideration that if you are using the smaller bracket you are going to need to put in a new mounting screw in the side so you need to make sure you give yourself enough room. Next we will take our Prodigy controller and mount it into position. To provide a little bit more clearance I am going to use the upper mounting holes in the bracket. Next with our controller mounted we can just take our wiring harness and route it across over to the Prodigy where we are going to plug it in. You can see instantly with it plugged in we have got NC flashing on our Prodigy brake controller. That is indicating that we do not have a connection to a trailer. That will blink a few times and then it will go to two dots. If you have any loose hanging wires left over from our connection you want to secure those up and out of the way. Then we can start to reinstalling the interior of the vehicle. Now that we have got the interior reinstalled we are going to plug our trailer in to our 7-pole at the rear. You will see that when we do that we have a C on the display screen of our Prodigy that is showing that we now have a connection. Now when we hit our brake pedal we get digital read out on the screen that lowers when you use the slide bar. With that, that will conclude the installation of Prodigy brake controller part number 90185-3040P on a 2004 Toyota 4Runner.

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

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

2008 Toyota Tacoma

We 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

They are still working great. We were under the gun at the time trying to comply with new commercial vehicle rules, and your products AND ESPECIALLY your website was a very valuable resource. Your tutorials are awesome. Thank you for being a resource rather than just a retailer.

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

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

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


Comments

Just a quick note, the controller has an automatic shut-off. After 15 minutes of the truck powering off and sitting still, the control powers down. As soon as it sees movement, it powers back on.

So you ran ground to negative side of battery? Or just on the frame interior somewhere?

-- comment by: Trevor - 06/29/2014

For 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.

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

Installed 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. 96004

etrailer really helped me. We rented and Rpod for a trip from Denver to Macon, Missouri. We have a 2016 4runner and I needed a brake controller. I was in over my head and tried to have someone install one for me, but it was expensive. So, I found the right one with the help of support staff and installed it myself. Was easy once I found the stock connector in the 4runner. I used velcro to mount it to the under side of the dash since we wouldn't need it full time. That worked for the most part. Toward the end of the 22 hours of road time it started falling off though. Brake controller was easy to use once I tried a few settings. 705228
