Install your electric trailer 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 port in your vehicle.
Features:
Note: To illuminate your vehicle and trailer brake lights when you activate the manual override on your brake controller, use this adapter in conjunction with the Tekonsha brake controller converter with 7-way adapter (30235-P - sold separately). Required for use in the state of California.
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 cutting or splicing of wires to install. It is designed to plug directly into your electric brake controller for the simplest installation possible. Because there is no hardwiring, installation is not permanent. You can unplug and remove your brake controller at any time and securely stow it away.

Today we're going to be taking a look at the Tekonsha 00:00:03 custom wire and adapter for trailer brake controllers. This product is going to fit certain years of the Toyota Forerunner. The plugin wire and adapter allows for quick, simple installation of your electric trailer brake controller. The wire and harness is going to measure overall about thirty inches long. It does not require you to cut or splice any wires for the installation. The custom connector end right here is going to plug into the built in port in your vehicle.
The included instructions, they are going to be very detailed. These are going to walk you through the installation process step by step and they're going to show you exactly where that port is. The plugs are going to plug into one another for a nice, tight, secure fit. They are going to snap lock together. The white wire on this unit is going to be your grounding wire. It's got a ring terminal already attached to the end of it.
You need to find a nice, clean metal surface to secure it to, and you can secure it with the self tightening screw. The other end is going to plug into the back of your electric brake controller. This is designed to be compatible with proportional brake controllers from Tekonsha, so it should just plug right in. Again, its got the locking tab up top so it's going to allow for a nice, tight, secure fit. The brake controller must have the built in plug for the adapter to connect.
This will not work on controllers with pig tail 00:01:16 wiring harnesses. After you plug in the connectors it will be fully installed and after you make the ground connection.One of the neat things about this is it's going to have a protective mesh that covers up the wires, so it keeps the wires all bundled together for a nice installation. It also eliminates wires from hanging down around your feet. Now because there are no wires to connect to the brake controller the installation is not permanent. What that means is that you can unplug and remove your brake controller at anytime to transfer it to another vehicle or securely stow it away. That's going to do it for our review of the Tekonsha custom wire and adapter for trailer brake controllers..

The wiring for the Tekonsha proportional brake control fit my 2016 4 Runner perfectly. Plus the videos that etrailer has showing where the plug in is under the dash made finding it a cinch. Thank you so much etrailer- Anthony, one of their staff even sent me the links for the wiring and the brake controller videos so I wouldn't have to hunt for them. Amazing staff- very helpful. Thank you so much. 347387
Thanks for asking. It means a lot that your company cares about products and service. Ive been very impressed with your company and the information that you provide. The brake controller works very well and is a very good product. Ive been very pleased with it. We went on a long trip from South Carolina to Montana. On the way we stopped by Mount Rushmore. Were going up a steep grade almost 10. Coming down it was nice that I could adjust the controller For more brake power. Thank you so much

I ordered this product from Etrailer ( 3041-P). It is made very well and the instructions for plugging it into my 4Runner were spot on. I needed to confirm of fit and availability and talked to there customer service Rep Christina. I was delivered to my house in just a day or two. 484301

Pretty straight forward installation on my 2016 Toyota 4Runner. Finding a place to mount it without drilling a hole anywhere was a bit challenging but I think we have that solved. Unit is quite substantial and solid but we've not yet tested its function. However, based on past reviews from others, I have no reason to believe there will be any issues. 459487

Purchased Brake Controller and Wiring adapter. It was just as easy (or even easier) an installation than described. Dealer wanted about $150 to "wire" my brake installer. I noticed this product on-line and read reviews and decided to see if it really was what it said. It took my son around 10-15 minutes to get it mounted and ground. When plugged into trailer, it worked!! When contacting Customer Service, I was very impressed. 385568

Having the ability to input vehicle year, make, and model really helps in getting specific product. Very easy to do. Price checked product online with several other websites and it was equal or withing a couple bucks. Free shipping was a plus and excellent packing. 444317
by: Brian08/22/2017
Installation took less than 2 minutes and I didn't even need the directions! (Toyota 4 Runner has wire connections in place from the factory.) This one seams to be a little longer than the OEM part, which allowed me to set the controller out of the driver cockpit. I was concerned hitting my knee on the controller, so that was handy. 423932
by: Mike M08/08/2017
As always, super fast shipping from etrailer and the part was in stock. Not much to say about it, works as stated, just plug it in to the harness under the dash and your Tekonsha is up and running. 417604
by: SRWNC08/08/2017
Worked like a charm. Installed easily in 2014 4Runner & 1997 Chevy 2500. No problems, no hiccups, no glitches pulling a 7x20 12k flatbed. etrailer.com videos, specifically installation videos are very valuable and one reason I keep coming back to etrailer.com. The folks where I bought the trailer said I made a great choice with this controller. I couldn't agree more. 417490

Shipped super fast! 328128
Still loving it! Works great and I’m not always towing so it’s nice to be able to unhook it and store it in my glove box, since I don’t really have a good spot to mount it in my truck. Great product!
Kristen j - 12/28/2017by: Ottis B.11/24/2016
Plugged in to 2016 4Runner TE and Tekonsha Voyager brake controller. Works great. Easy install. Be sure to connect white ground lug to a good metal grounded location. Simple to install and price is great. 319350
