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.
Features:
This adapter plugs into the 4-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.

Today we are going to cover a frequently asked question. It really turns up a lot. And actually it is easier than you think. Basically, if you have a pickup and you got a tow package with it and you got one of these wire harnesses that plug underneath the dash and plugs into your brake controller, you might have five or sometimes even more wires coming off of it. And you notice that your brake controller only uses four. We have got one over here, we will show you, that has just the four wires and what do you do with the extra wires? The short answer is do not worry about it, because the brake controller has all that it needs from these four wires.
To give you an idea of what is going on, most of the time these harnesses are labeled as to what color does what. So this one will say TO TRAILER ELECTRIC BRAKE. That means that this is going out to the trailer itself. So if you look on the your brake controller, it is going to be the blue wire here, so those match up together just like that. The next one is labeled GROUND, so you go to the wire harness on your brake controller and find the one that is labeled GROUND in this case it is going to be white, also. And then the next wire, here, we do not have a label because the label fell off, but this is the 12 volt power supply wire here. A lot of times the brake controllers come with a little handy card that tells you what does what on the OEM harnesses, also. The thicker wire is usually going to be your power supply. So that would go to black, the 12 volt power supply wire on the brake controller.
Then you have the two wires left, the green and the brown. The green is labeled STOP LAMP, so that will go to the stop lamp circuit on your brake controller, which in our case will be red. And then you have the extra wire here, which is labeled ILLUMINATION FEED. Basically, this comes on when you turn on your running lights. So if you have something you need to power on the inside of your vehicle, for running lights you could possibly use this. But for towing purposes, I do not really know really what you could use this for no brake controller ever uses this. So basically all you do is just fold it back out of the way, tape it up so it doesnt short out against anything, and do not worry about it.

I purchased the Tekonsha P-3 and the plug and play harness for a 2006 Dodge ram. Cathy of etrailer was very helpful. I was concerned about shipping and Cathy promised that she would get it out that day. Sure enough I got a follow up e mail letting me know that it went out that day. I even got an e mail letting me know that it has been delivered. Outstanding customer service! 31726

I purchased a P3 brake controller and wiring replacement for my dodge ram truck from E-Trailer and could not be happier with the service and the products. My order was delivered very quickly. The wiring replacement was as good as the OEM part that originally came with the truck. Installation was plug and play once I decided where I wanted to place the bracket for the controller. If this 53 year old lady can do it, anybody can. It was easy. I might add that I shopped around to see what I could get this same controller and wiring for locally and the cheapest was over $100 more than I spent for the same components from E-Trailer!7615

Installation was a breeze, I used it last sunday towing my stock trailer, the digital display is nice. The gal I spoke to at etrailer was very helpful for me while deciding which controller to install. I regularly tow a 16' steel stock trailer as well as occasionally tow brick and masonry materials, the p3 proportional was a major step up from my old school drawtite electric controller. The self leveling feature of the p3 has already been helpful for me. I am pleased with the product. 42792

This is the second time I've ordered products from Etrailer. They shipped the products extremely quickly (both times) and I received them substantially earlier than expected. I previously ordered a Prodigy brake controller and all the parts needed to do a full install, since my truck was not wired for a trailer. I just purchased a 2006 Ram 3500 and used this cable to connect to the factory harness. It worked as advertised and I was able to reuse my exisiting controller without any problems. I will definitely be using Etrailer for future purchases based on their excellent customer service and pricing.22503

Installed on a 06 Dodge 3500 Mega Cab. This is as advertised, but it's only about 24 inches long. If you want it to reach the center console you will need to splice in about 12 - 16 inches of more wire, but it's still much easier than splicing the factory wires under the dash.9866
