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 - 2013 Toyota Tundra

Today, on our 2013 Toyota Tundra, we'll be installing the Tekonsha Prodigy P3 Brake Controller, part number 90195. In conjunction with the Tekonsha Plug and Play Wiring Adapter, part number 3040-P. To begin our install, we'll first go ahead and mount the brake controller bracket. For this application, I'll be using a couple of self tapping screws or you can also use the screws provided with the brake controller install kit. Once we have the brake controller mounted, we'll then go ahead and set the brake controller in the bracket and secure it with the screws provided in the install kit. Next, we'll need to go ahead and plug in our Plug and Play Wiring Adapter. Before I install the wiring harness, I'm using black electrical tape to wrap up the wires to hold the ground wire to the harness and to clean up our install look. Now with the taped up, we'll go ahead and take the white connector and plug it into the manufacturer's towing port, that's located on the driver's side, just above the kick panel and between it and the parking brake pedal. Now, with that connection made, we'll take the white wire, with the pre-attached ring terminal, which should be the ground wire for our harness, and secure here it to a body ground, which our parking brake pedal bracket is grounded so we can use our self tapping screw and secure it directly to that. Now, with those connections made, we'll go ahead and route our wire back over to the brake controller and install it into the back of the brake controller. Now we have it routed and installed, I'll go ahead and use a couple of black zip ties to secure our wiring up underneath the dash, and then we'll cut off the excess from the zip ties to clean up our install look. Now with that, we're ready to hit the road. That's about it the install of the Tekonsha Prodigy P3 Brake Controller, part number 90195, in conjunction with the Tekonsha Plug and Play Wiring Adapter, part number 3040-P on our 2013 Toyota Tundra. .

2013 Toyota Land Cruiser

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

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

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

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

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.

    The Tekonsha Plug-In Wiring Adapter for Electric Brake Controllers - Toyota and Lexus # 3040-P is a great option for Tekonsha brake controller wiring in the traditional location. However, because you desire the controller to be a part of your console, there are better options available for that fit.

    The brake controller wiring harness for the P3 and your 2012 Toyota Tundra, # 3040-P, does include a separate ground wire that you will need to attach to a bare metal surface on the truck. The factory ground in the Tundra is not sufficient for the needs of the brake controller which is why this additional ground wire is needed.

  • Why Does Brake Controller Install Port of 2012 Toyota Tundra Have 5 Wires When Only 4 are Needed
    That fifth wire would not be needed on the brake controller install connector of your 2012 Toyota Tundra. The reason that circuit is there is for basically turning on a brake controller display light with the vehicle headlights. The p3 (and all of the Tekonsha controller), do not require this as their displays are always bright enough to be seen. It has nothing to do with powering your trailer running lights as that's on a totally separate circuit. So all you need are the 4 wires...

If you do not have a trailer connector at the rear of your vehicle you would need to go a different route. You will...

    The harness you need to install the Brake Controller Adapter part # 3040-P will be located underneath and left of the steering column, taped to another harness near the emergency brake pedal.

  • Recommended Trailer Brake Controller for 2015 Toyota Tacoma Towing 13-Foot Scamp Trailer
    Our customers have told us again and again with their purchase decisions and product reviews that the Tekonsha Prodigy P2 trailer brake controller, part # 90885, is easy to set-up and operate and is supremely reliable. This is a superbly engineered brake controller that is a snap to use. Installation method will depend on whether or not your Tacoma has a factory-installed 7-way trailer connector at the rear bumper. If you do have a 7-way then installation will require only the controller...

    I attached a picture that shows which connector to use as well as an install video that shows the # 3040-P being used to install a brake controller in a similar 2004 4Runner.

  • Locating Brake Controller Port Under Dash of 2007 Toyota Tundra w/ Factory 7-way
    I contacted our representative at Tekonsha and he informed me that the plug should be located under the dash to the left of the brake pedal or behind the kick panel. The plug will more than likely be tucked up behind wires behind the kick panel (see video link at :35 second mark). If the 7-way on your 2007 Toyota Tundra is factory, then you will be able to install your brake controller using the wiring adapter, Tekonsha Wire Replacement, part # 3040-P. The item you selected, Tekonsha...

  • Wiring a 2008 Toyota Highlander Hybrid with a 7-Way Trailer Connector and Brake Controller
    If the wiring that was done tied directly into the tail lights of your 2008 Toyota Highlander but did not have a converter, that may be the reason it was throwing codes. In order to install a 7-Way trailer connector on your Highlander, you will first need to install a 4-Way wiring harness, # 118449. I have included links to the installation details and a video showing a typical installation. Next, you will need to install a 4 and 7 Way Installation Kit, # ETBC7. This provides a 7-Way...

  • Recommended Brake Controller for 2010 Toyota Tundra Towing 7000 lb Travel Trailer
    Brake Controllers are not vehicle specific, so just about any controller would work for you. This being said, I would recommend you go with a proportional type brake controller. A proportional controller features an internal sensor that can determine how quickly and at what intensity the tow vehicle is braking. The controller will then send the appropriate amount of voltage to the trailer brakes so that the trailer and tow vehicle stop at the same rate. This makes for a safer stopping action,...

  • 2015 Sequoia SR5 Brake Controller Wiring Harness Location
    On your 2015 Toyota Sequoia SR5, the harness to connect the # 3040-P is located underneath the dash, to the left of the steering column, taped to another harness near the emergency brake pedal. I've attached a video to assist. It is tucked up there and not extremely easy to find. If you don't have the tow package and the wiring you mentioned was added by the dealer or a previous owner, then you will need kit # ETBC7 to complete your vehicle brake controller wiring.

  • Is the Extra Ground Wire Required to Install a Tekonsha P3 Brake Controller in a 2013 Toyota Tundra
    Yes, you will want to ground the additional white wire of the Tekonsha Plug in Wiring Adapter part # 3040-P to install your Tekonsha Prodigy P3 Brake Controller part # 90195. The additional ground is necessary for aftermarket controllers like the P3. When we installed this harness on a very similar Tundra as yours we used a self tapper and drilled it into the sheet metal by the emergency brake pedal. See the video I attached. Fast forward to the :30 second mark to see exactly where.

  • Will the Tekonsha Plug-In Wiring Adapter # 3040-P Work on a 2014 Toyota Tacoma
    The Tekonsha Plug-In Wiring Adapter, # 3040-P, will work on your 2014 Toyota Tacoma as long as your truck came with a factory installed trailer wiring. The factory connector for this harness is located just above the emergency brake pedal. If you are looking for a brake controller as well, I recommend the Tekonsha Prodigy P2 Brake Controller, # 90885. This is one of the most popular brake controllers on the market. I have attached an installation video of this brake controller and the...

  • Adding a 7-Way and Brake Controller to a 2012 Toyota Tacoma with Aftermarket 4-Way Connector
    To install a 7-Way and brake controller on your 2012 Toyota Tacoma that did not come with a factory 7-Way the parts will need to be hardwired in. There isn't a plug and play 7-Way option for your Tacoma. Since you already have the 4-Way installed you will just need # ETBC7 and the brake controller. I recommend the P2 # 90885 because it's easy to set up and use and it is reliable. Installation will be very similar to the video on the 2009 Tacoma which I have linked for you. I have...

  • Brake Controller and Installation for a 2014 Lexus GX 460
    On your 2014 Lexus GX460 the Tekonsha Plug-In Wiring Adapter # 3040-P that you referenced would simply plug into the connector you found. The brake controller only needs 4 of the circuits in your connector to function. The battery power supply, stoplight circuit, ground, and brake output to run to your factory 7-way. The additional ground wire should be run to a metal surface near the connector. The Toyota ground is not sufficient for aftermarket brake controllers. There should be a...

  • Brake Controller Installation-2005 Toyota Tacoma
    According to my contact at Tekonsha, the # 3040-P is the correct brake controller wiring harness for a 2005 Toyota Tacoma IF the vehicle is equipped with the factory 7-way trailer connector. The # 3040-P is compatible with all Tekonsha brake controllers that have either the socket in the rear of the controller for the harness or those that have the wires that extend from the rear of the controller that terminate in a connector. If your controller has wires that exit the controller and terminate...
