Question:

Hey I just received my p3 controller and you included a wire harness that has a brown end. Im assuming thats to plug into the vehicle nut not sure where the plug is at. All i have found are the 4 wires on the left taped to the large cluster. Lemme know if there is an actyal plug or do I just splice these wires? Thanks

There will be no port under the dash of your 2006 Chevrolet Trailblazer, but after removing the kick panel you will find a cluster of wires, with the wires you need identified with a piece of white tape or paper.

You will need to free those wires so the P3 # 90195 can be installed. The wires on the vehicle will not match color to color so you will need to attach them in the following manner. The black wire from the brake controller attaches to the orange wire on the vehicle. The blue wire on the brake controller matches up with the blue wire form the vehicle. The white wire from the controller gets attached to the black wire form the vehicle, and the red wire on the controller harness connects to the light blue wire on the vehicle.

I have attached a link to an installation video for a P3 controller on a Trailblazer you can check out. I have also attached some helpful articles you can take a look at.
