Does anyone have the wiring code for an 02 Avalanche 2500 when installing the electronic trailer brake controller from tektronix? I need the wiring code for the harness that comes with the vehicle. It is normally attached to the harness, in the glove box, and i had lost the tab with the wiring code.

Any help will be greatly appreciated.

sorry it is a tekonsha voyager prodigy brake controller. i need the wiring harness side of things for the color code. thanks again

This should show the change that was made in 03 for the GM trucks wiring harness.
