Trailer Brake Controller Installation – 2012 Chevrolet Silverado – etrailer.com


All right, today on this 2012 Chevy Silverado,
we’re going to install part #90885 from the inaudible. This is the P2 brake controller. First thing we need to do is go ahead and
find the factory wiring harness on our truck. Now it’s located behind the dash underneath
the steering wheel just a little towards the left and a little bit left of the brake pedal. Now it’s pretty far up in there so it’ll take
a while to find. Now, take the wires and let’s gently pull
them down. All right, when you look for the wires, you
will look for this bundle right here with the dark blue wire, bright orange wire, a
light-blue wire, a white wire, and a red wire with black stripe. There’s five wires here but we’ll only use
four. We’re going to use the red with the black
stripe, that’s our 12-volt battery feed. We’re going to use our blue wire which is
our output from our brake controller including that to the trailer connector. Our all white wire which will be ground and
our blue wire with the white stripe, that’ll be a signal coming from a
brake switch.
