Every now and then, a vehicle is made that has a brake controller wiring harness with 5 wires like on your 2008 Nissan Titan. All 5 wires are not necessary to allow the brake controller to function.

On your truck, the red/green wire marked brk sig will attach to the brake controller red wire for the stop light.

The black wire marked gnd is the ground and will attach to the brake controller white wire.

The brown/white wire marked brk out will attach to the brake controller blue wire for output to the electric brakes.

The red/blue marked ill will not be used. This is for illumination. The Voyager brake controller does not have an illumination feature.

The red wire marked fused B plus will connect to the brake controller black wire. This is the connection to the positive battery terminal via a fused connection. It provides power to the brake controller. I have also included a link to the Voyager instructions below. I have also included a link to an FAQ article on brake controllers that has the above information near the bottom of the page.
