Expert Reply:
I have linked 2 articles below on the installation of the Tekonsha Brake Controller # 90195 on your truck that I would like you to reference. There are 2 different wiring articles, one for certain trucks that came with an integrated brake controller and the other for vehicles that did not. Be sure to check this on your truck as there is a different installation process for vehicles that have an integrated brake controller.
