12-10 Gauge Butt Connector

Video Transcript for Trailer Brake Controller Installation - 2011 Nissan Pathfinder

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.
