Availability of Brake Controller Wiring for a 2010 Nissa Xterra with Factory Tow Package

Question:

I have a 2010 xterra with a factory towing package. I am assuming all I need is the wiring harness? And not the install package? So when this is installed, it all goes to a single wire on the 7 blade connector? Can the two brake wires simply be tied into one on the trailer side? Thanks.

Currently, there is no wiring harness made for the 2010 Nissan Xterra with a factory tow package. If it is anything like the 2010 Nissan Titan, there should be a factory harness located underneath and left of the steering column, taped to another harness near the emergency brake pedal. It is a 6-pin connector that mates with the # 3050-P brake control wiring adapter.

I recommend checking ahead of time to see if the harness is there. If not, you will need to hardwire the brake controller wiring as follows.

The white wire will need to go to the negative battery terminal and the black wire will need to go to the positive battery terminal. You can use a length of # 10-2-1, make the connections at the brake controller and then route the wiring through the fire wall to connect to the battery. For the blue wire, you would need # 10-1-1 wire with enough length to reach the 7-Way trailer connector. Route the wire under the vehicle, avoiding areas that may pinch or burn the wire, and connect it to the pin in the 7 oclock position at the back of the plug.

For the red wire, you will need to use a circuit tester like # PTW2993 to find the wire on the brake switch located above the brake pedal that carries a signal ONLY when the brake pedal is pressed. Connect this wire to the red wire on the brake controller.

There is just 1 pin for brake output on the 7-Way. On the trailer, each brake will come together as 1 at the trailer connector.
