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 junction box beneath your vehicle's dashboard.
Features:
This adapter plugs into the 6-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 in this 2011 Nissan Pathfinder we're going to install part number 39510 from Tekonsha. This isthe Voyager trailer brake controller.This vehicles already been equipped with a 4-pole wiring packaging from the factory. To add ourbrake controller and connector, we're basically going to just fill in the blanks. We're going to start offunderneath the dash. We're going to locate the tow package port underneath the dashboard whichis going to be just right of the steering wheel, behind the dash, and also a little bit above thediagnostic port.We'll go ahead and take the adapter cord and plug it into the brake controller, and then we'll goahead and plug it into the port underneath the dash. The part number for our adapter cord will be3050-P.
With all the brake controller wires plugged together, we'll go ahead and add the bracket tothe dashboard underneath. We're going to locate it next to the diagnostic port, just a little bit to theleft of it. We'll use two screws to attach the bracket to the dashboard.Next we'll pre-drill the holes in our brake controller to accept the hardware; we'll install the brakecontroller to your bracket using four more screws; and then we'll go ahead and take a moment to ziptie our wires and make sure they're safe and out of the way. Then we can go to the back of thevehicle. Thats where we're going to go ahead and add our 7-pole connector to the back of thevehicle.
Thats going to be part number 37185. We're going to take the bracket and hold it to thebottom of the hitch. Theres an existing weld nut we're going to use to fasten it to the hitch. We'llhold it up there, make a mark on the bracket, and then we'll go ahead and drill it out to a 3/8 hole.We'll take our bracket back to the vehicle and attach it to the hitch, using an 8 mm bolt, the 1.25thread hitch; then we'll go and add our 7-pole connector. On the 4-pole end of it we're going toapply some dielectric grease and then attach it to the factory 4-pole.
We're going to run a zip tiethrough the wires to make it a semi-permanent connection. We'll take a moment to tape up ourwires and also add our loom material to help protect some of the wires and make it look nice.At this point we'll go ahead and connect the 7-pole to the bracket, and then we're going to add alength of wire to it about 3 or 4, part number 10-2-1. We'll cut the sheath back and we'll have ablack and a white wire. We'll run our black wire to the black wire on the 7-pole connector and ourwhite wire to the blue wire on 7-pole connector. We'll crimp those down and then use some tape tohelp protect them.There are two remaining wires left.
Therell be a white wire for the ring terminal and a purple wirefor the buck connector. We're going to tape those two wires to our grey cable, and we'll run thosewires along with the grey cable. Now we're going to route our cables over to the end of the towpackage which is located next to the spare tire. We'll measure a length of a grey duplex cable weneed and cut the excess off; then we'll strip back to the sheath of the grey cable, exposing the wireswe'll need later. Then we can take the white wire with your ring terminal and ground it to the frame.The self-tapping screw we'll be using will be part number SA1131822.We're going to look for a connector thats at the end of our tow package. We've got a smallconnector with two wires going to it. There will be a brown wire and a purple wire going to it. Now,we dont have a connector to match that, so well rotate the connector and remove it from thewires; then we'll go ahead and crimp our wires from our grey cable to those two wires. We'll use abuck connector to make those connections. Our part number for our buck connectors we'll be usingwill be part number 05732-2.We're going to connect this as follows. Our white wire which will be our brake controller output isgoing to connect up to the brown wire; and then our other wire, a black wire, will connect up to thepurple wire. Thatll be our 12 volt power supply. We'll go ahead and tape up our connections and ziptie our wires safe and out of the way.All our connections are done at the back of the vehicle; now we'll go underneath the hood and wehave to add one relay to power our 12 volt power supply. Theres a relay box closest to the battery.We'll remove the lid and you'll see that theres two relays already installed, and therell be an opensocket for an additional relay. We'll install the relay for our 12 volt power supply, and thats going tobe part number V38937-1.With all of our connections made, we'll go ahead and test out the brake controller. We'll plug atrailer into it and you'll see that the LED on top will turn from off to a green color; and then we'll usethe manual override. You'll see that goes from a green, to a yellow, to a red that shows the manualoutput works. Now we'll go ahead and try the foot brake. We have to make the level in the brakecontroller a little bit more aggressive, so we can see it work. Push down the brake pedal and you cansee that turns from a green to an orange.And with that, thatll finish it for our install of our Voyager brake controller on our 2011 NissanPathfinder.

I have a 2005 Nissan Titan with factory tow package. The connector was a perfect fit and long enough to mount underneath the dashboard to my right. The factory installed pigtail is located under the dash above the emergency brake pedal. It's actually marked with a tag that says "brake controller". 49268

Excellent harness! Just like the factory if not exceeds the OEM. I got the P3 brake controller with the Nissan Harness and it just pluged right in and done. Took me 15 minutes just to mount the controller where I wanted it. Otherwise it is a breeze. No need to have it sent to the dealer or garage to have this installed. Do it yourself!!!! The controller comes with everything you need to install it. I highly recomment getting the wire harness. well worth the money and no aggravation in splicing and running wires. 48618

Installed in 2013 Frontier Kingcab with 7-wire Nissan factory harness. With the Tekonsha wiring adapter it simply plugged-in, cable-tied to the under-dash wiring and was done. Rather than drill the dash for the mount, the mounting bracket was velcro'ed (adhesive backed) to the flat area between the seats (slightly under the dash). See attached picture. Appears to be functioning well with no issues.80178

The trailer dealership wanted $350 bucks to install a lesser brake controller in my wifes armada. This was sooo easy to install with the harness ( vehicle harness needs to be bought separately from etrailer for cheap). What an easy install for leas than half the price of having the dealer install. Thanks guys. Patrick64536

it's great to have a adapter that I can just plug into my wiring harness. The one that the auto company sells has to be spliced into the controller and cost twice as much. I love my adapter harness I got from etrailer62846

Made it a breezy to use, no connectors to splice into my harness from the factory, just plugged into the truck and I'm ready To tow. Also a piece of mind know there are no splices to fail between the harness and break controller. Dont skip out, it's a couple bucks more, but wroth it 62324

What a fantastic product! I ordered the Tekonsha P3 and the plug-in wiring adaptor for my 2009 Nisan Titan w/ tow package. With factory plugs at both ends, the wiring adaptor made the most difficult part of the project finding the right place to mount my new brake controller. The P3's adjustability allowed me to set the display color to one similar to my truck's instrument lighting creating a "factory" appearance to the installation. I haven't used this product for it's intended purpose yet (towing my to-be-delivered toy hauler), but I have used it to tow my parent's new travel trailer. A wide range of adjustability at a fantastic price make this a product I would recommend. Additionally, I was so impressed with ETrailer that I immediately ordered the Teconsha P3 and a complete wiring harness for my parent's 1999 Toyota Tacoma from them as well.56132

Wow. The only way the installation would have been simpler is if someone would have done it for me. With this wiring harness, my brake controller installation literally took less than 5 minutes (including zip tying the wire under the dash, out of the way, and mounting the controller itself to my console).23770

After asking my Nissan dealer how much they would charge to hook up my trailer brake module, I decided to reseach the net and found than etrailer.com had exactly what I needed to "plug and play" my brake control to my truck. The order was easy, delivery was quick. Product arrived well packaged and in perfect condition. I had the control mounted and plugged in in a matter of 30 minutes. Thanks for the good service.16313

The product functioned exactly as listed in the product description. I only found one thing frustrating, and that was how Nissan buried the plug under the dashboard. Regardless, after popping out two screws, I was in business. The whole procedure took about 15 minutes, and that included searching for the pigtail. As always, etrailers directions were very easy to follow.14298
