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.

Replaced a time delay controller with a Prodigy P2 and the adapter harness for a 2008 Tundra towing a 5th wheel camper. Used existing mounting holes to the right of the hood release for the new bracket, so installation took about 10 minutes. Had to be careful routing the harness around the e-brake pedal but a strategically placed zip tie did the trick, the extra length of wire was tucked neatly behind the plastic "kick guard". After warming up the brakes, as recommended, it took less than 10 minutes to get calibrated. Gotta say I'm not missing the "pull and tug" , especially in stop and go traffic. Haven't made any long trips yet but initial experience has been very favorable. 424282


Comments

Have towed 1500-2000 miles using this controller. Occasionally have to adjust braking intensity due to driving conditions, but the roller adjustment is easily accessible from the driving position so I can adjust “on the fly”.

The harness is an excellent timesaver and makes the brake controller install much easier. The only suggestions I have for the manufacturer are to offer the harness in different lengths and to move the pigtail for the ground wire to the other end of the harness. I installed my controller in my console and it required me to lengthen the harness. I didn’t want to remove the whole console to find a ground location so I installed the ground on the other end of the harness where it connects to the truck’s wiring. There are ground locations aplenty in that area of the floorboard. 556327

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

Well, you may not see the actual brake controller in these shots, but I wanted to display just how much etrailer product was used to restore this old trailer. Re-decked the trailer, new wheel bearings, added brakes on all 4 with this brake controller and battery powered emergency disconnect... new rust protection, primer and paint, new lights and wiring all the way around, new wiring harness/box, and new tire carrier. Nearly all product except the decking and paint was from etrailer. the customer support was fantastic, I highly recommend this company! 546744

Well just as a quick background to let people know I am not a mechanically or electronically inclined individual with that said when I called and ordered this product tech-support stayed with me talk to me through the process of how to look this up and where to find the actual connections which were completely different than anything I saw on YouTube or online and the installation was absolutely the simplest thing I’ve ever done on a vehicle ever so I am completely happy and 120 percent satisfied with not only the product but Support As well. I will definitely purchase products in the future and will absolutely recommend this to everyone that I know. 460407

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

Harness is a bit short and the hole in the grounding eyelet is 1mm too small to mount where suggested in the video (brake pedal mount). Controller worked fine without, I was in a hurry so I didn't mount but will now. I will splice together with the cable that came with the P3 to add length. 548540

My car came with a harness but it didn't have the connectors on both ends. This little harness worked perfectly for my 2012 Sequoia because it snapped into the back of the brake controller and into the manufacturer's plug. I had trouble finding a good spot to connect the ground wire but I found a video on etrailer.com that showed me exactly where to find an excellent location behind an easily removed panel. 545755

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. 120012

This is the first brake controller I have ever bought. I just brought home a new Toyota Tundra and a travel trailer. I didn't have the opportunity to have the dealer install a brake controller so I called ETrailer and had them ship me one next day. The controller is great. I hooked it up and mounted it on the left side of my dash. Plugged right in to my factory prewire. The only issue was I had to find a place to ground the unit, but I was able to do that by removing a panel by the emergency brake and attaching to a ground there. The installation was simple and easy. I setup the controller from the manual - which is easy to ready and well written. I did the test runs as indicated in the manual and what I gleaned from other sources and the trailer brake controller works exactly as it should. There are more features on this controller than I probably need, but it looks great and works exactly as described. I am very satisfied with the purchase. 91459


Comments

Its been almost 18 months and the controller is still working great. Ive put nearly 10,000 miles of use on it and my only gripe is that its hard to change boost settings while in motion as the size of the screen is a bit small. I didnt mount it in the most visually accessable place either though. I still highly recommend the product.

Purchased Adapter along with controller. Could not be more pleased. Was under a time crunch, new truck + next day horse show = quick install and dial in. The process went flawless - 15 minutes to install and be operational and then 10-15 minutes to setup the way I wanted and dial it in for both the empty trailer and full trailer. The Adapter went along way to this simple instllation. 60489


Comments

I sincerely appreciate your follow-up and I can assure you that when need something else that you carry, we will be in contact. The Break Controller works wonderful - I have it programmed for my horse trailer in a light load configuration, a full load configuration and then the 3rd trailer configuration the controller allows, I have programmed for my utility trailer - I would highly recommend this controller and you to anyone.

I've never hooked up a trailer break controller before, but the videos that etrailer provides gave me confidence; detailed video and exact step-by-step instructions. Kudo's. One point I'd like to make - not sure why the ground lead was not included in the pigtail. Perhaps they found that some OEM connectors were missing this lead. But since it wasn't, I had to open and pry the terminal to fit the only available bolt which slowed down the installation job, but I got there. Might recommend the pig-tail maker to use a bigger terminal ring. (white wire) I've still not actually used the product, but it appears to function as advertised. I won't be hauling until spring (Mar/Apr, depending on weather), but I'm ready. Again - great instructions from etrailer which ultimately lead me to purchase this product. 66935

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.

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

The cable is well made and installs quickly. The only thing that would have made it better is making it about a foot longer. Its current length limits mounting the P3 to the left of the steering column. 147951


Comments

Would you believe that I havent used my controller yet? I got it because my son borrows my Tundra when he tows his 12 trailer out of state. Since I bought the unit, he hasnt gone on a long trip. I can say, however, that when the display of the original unit went bad, the unit was replaced promptly with a new one. The only thing that I would have changed was to make the connecting cable that you offer about 18 longer. That way, the unit can be installed on the right side of the steering column. I had to install my unit on the left side of the steering column, where it was partly in the way of my foot when I set or released the emergency brake. Other than that, I think Ill be happy with the unit.Sincerely

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

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

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. 134425

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. 281088

Product been working great. I even kept the console part and move it newer Tundra truck that I brought and bigger camper. Work better than I expected. I did use the bracket that come with the controller and mounted it. So I wouldnt have to worry about it coming loose or being in so far in the console. It also allow me to use the manual brake easily.

Product plugged in to my 2016 4Runner and the brake controller and seems to be working fine. I know it is pretty straightforward but it arrived loose in box with other items purchased. No instructions about what to do with that extra white wire. I assumed it needed to be grounded to the car frame but it would have been nice to have "instructions for dummies" just to be sure. That said it seems to be working properly. 576258

  • A proportional brake controller is definitely the way to go if you are looking for the best. The P2 # 90885 and P3 # 90195 will operate the exact same as they have the same internals. The difference between the two is that the P2 uses more of a traditional style of display that will show codes for error messages and connection status. The P3 will use a much larger display that will show actual phrases that won't require any deciphering, has a much better diagnostic setup, allows you...

  • Location of Brake Controller Port Under Dash of 2015 Toyota Tundra with Factory Tow Package
  • The brake controller port for the 2015 Toyota Tundra is located behind the section of the dashboard with the tow/haul button. To reach the connector you will need to locate the notch in the access panel in the center of the dash near the driver's side. Using a trim panel puller like # ALL648544, carefully pry the panel out and undo the locking tabs to remove the panel. You will find the mating connector behind this portion of your dashboard. The correct harness for your 2015 Tundra is...

  • Locating Brake Controller Connector on 2013 Toyota Tacoma with Factory Tow Package
  • Since your 2013 Toyota Tacoma has a factory tow package, including a 7-way connector at the back bumper, it will have a brake controller connector. While it is usually visible above the emergency brake pedal, it may sometimes be taped or zip-tied to other wiring. You can try checking further up under the dash panel. If not there, the connector may be tucked in behind the left hand kick panel. Please refer to the attached photo. The Tekonsha installation instructions for the P2,...

  • Towing Capacity of a 2013 Toyota Tacoma 4.0 Double Cab 4x4 with Factory Tow Package
  • I can help you out, no problem. What you are going to want to look at is the towing capacities of the truck. You need to know the gross combined weight rating. This is the most the vehicle, including cargo and occupants, plus the trailer can weigh. This information is usually in the owners manual or on a sticker in the door jamb. Looking at an online copy of the owners manual the 4 liter V6 model of the 2013 Toyota Tacoma with 4-wheel drive could have one of several capacities depending...

  • Brake Controller Installlation- 2013 Toyota Tacoma
  • It is not difficult to determine if your Tacoma has the tow package wiring in place. If your Tacoma has the OEM 7-way trailer connector installed, the vehicle is indeed prewired for a brake controller. The # 3040-P wiring harness would plug into the connector located near the emergency brake pedal as shown in the photo I edited for you. Make sure the white ground wire with the ring terminal is grounded to bare metal under the dash. If you do NOT have the OEM 7-way, the plug for...

  • Brake Controller Installation in 2015 Toyota Tacoma
  • The # 3040-P is indeed the correct brake control wiring adapter for your 2015 Tacoma. Due to the presence of the knee airbag, the preferred location to the right of the steering column might not be feasible. If there's not a suitable location to the right of the steering column where the controller could be mounted so that it's parallel to the direction of travel, you'll need to consider an alternate spot. If you watch one of the videos I've linked you to, you can see the controller...

  • Blue Wire Showing Voltage with No Trailer Connected and When Not Applying Brakes on Brake Controller
  • It does sound like there is a short to the brake controller through the wiring or in the internal circuitry of the brake controller. Since your brake controller shows no red light this indicates a short to the brake line (blue wire). If you are using wiring harness, # 3040-P, make sure that extra white ground wire is attached to a clean bare metal surface. If it is hardwired to the truck, the ground needs to be connected to the negative battery terminal. Sever the blue wire a few...

  • Installing a Trailer Brake Controller on a 2013 Toyota Tundra with OEM Brake Controller Harness
  • It sounds like you have the factory brake controller harness so all you will have to do is plug the one end into the truck and attach the wires from the other end to the brake controller using butt connectors like # 05731-5. Your factory harness most likely will plug into the same place as the aftermarket # 3040-P. The plug-in port should be located under the dash, left of the steering column taped to another harness near/above the emergency brake pedal. I have linked the instructions...

  • Installing a Brake Controller on 2005 Toyota Tundra
  • The factory installed brake controller connector should be a white plug located on the left side under the drivers side dash on your 2005 Toyota Tundra Dual Cab. I have included a photo and a video that shows the location of the plug on another Toyota Tundra at the 8 second mark. This plug may not be there if your vehicle did not come with the factory tow package. The Multi-Plug, # 20137, is designed as a replacement if your vehicle came with a factory tow package that included the...

  • Brake Controller Install Port Location on a Toyota Land Cruiser
  • The connector you sent in a picture of is not the brake controller port. You would want to look for the female style plug that would match the connector in the picture I submitted. We have had customers state that the location of the brake controller port on the Toyota Land Cruiser is 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...

  • Brake Controller Installation on 2011 Toyota Tundra
  • If your 2011 Tundra has the factory tow package, which includes the factory installed 7-way trailer connector on the rear bumper, it will be equipped with the tow package plug under the dash, as shown in the photo I've edited for you. Some models with the factory 4-pole (or 4-pin) trailer connector will also have the plug under the dash, you'll need to look for a white plug located above and to the left of the emergency brake pedal, above the toe kick. Occasionally, the plug will be located...

  • Location Of Factory Brake Controller Port On 2007 Toyota Tundra SR5 w/ Tow Package
  • The connector should be located underneath the dash to the left of the steering column. It may be taped to another wire and tucked up and out of the way. I have linked a video installation of brake controller being installed on a 2007 Toyota Tundra using the # 3040-P adapter.

  • How to Install an Electric Trailer Brake Controller on a 2011 Toyota Tacoma with Factory Tow Package
  • The installation of the Tekonsha P2 Brake Controller # 90885 and Wiring Harness,# 3040-P, could not be more simple on your 2011 Toyota Tacoma with tow package. The truck will have a wiring harness up under the dash, to the right of the steering column (the plug could also be left of the steering column above the emergency brake pedal). All you have to do is plug in the brake controller wiring harness to it, ground the additional white ground wire to a bare metal surface or existing grounding...

  • Installing a Trailer Brake Controller on a 2014 Toyota Tacoma
  • If your 2014 Toyota Tacoma came with a factory installed 7-Way trailer connector then the plug-in for a brake controller should be there. Harness # 3040-P is the correct one for your truck and a Tekonsha brake controller. I recommend the P2 # 90885 because it is easy to set up and use and it is reliable. I have linked a video to the right that shows where the controller plugs in. This adapter plugs into the 5-pin connector on your vehicle's built-in brake control wiring harness. The...

  • Location of Factory Trailer Brake Controller Harness on a 2007 Toyota Tacoma with Tow Package
  • The factory harness to plug in a brake controller wiring harness on your 2007 Toyota Tacoma is located underneath and left of the steering column, taped to another harness near the emergency brake pedal. There will be a 5-pin connector that mates with the one on the adapter, # 3040-P. The harness does include an additional ground (white) wire that will need to be attached to a bare metal surface. The P2 is a proportional controller that applies the trailer brakes in proportion to how...

  • ABS and Traction Control Light Stays on After Installing Brake Controller on 2009 Tacoma W/Tow Pkg
  • My first suggestion would be to take your Tacoma back to where you had the controller installed. If you paid them to install the brake controller, I would expect that they should be responsible for correcting the problem for you. According to my contact at Tekonsha, there a few possible causes for what you have occurring. The most likely cause is that your emergency brake is partially engaged. Pull the release handle to make sure the emergency brake is fully disengaged. You might need...

  • Installing a Brake Controller on a 2003 Toyota Tundra with a 7-Way but Not a Tow Package
  • As you probably know, in 2003 Toyota made the Tundra with or with out a factory trailer connector. So if they installed one when you bought it, they might not have run all the wiring for a brake controller. This might be why you only see 4 wires at the 7-Way. I believe this is the case, so you will need to hardwire the brake controller. You will need a brake controller. I recommend the Prodigy, # 90885. It is one of our best selling and highest rated controllers. There are two possible...
