    Does anyone know how to obtain wiring diagrams on a Peterbilt. I’ve heard Fleet Ecat is a way to get them, if so how would I be able to through that website?

    You have access to fleet WebEcat and Paccar.net/ServiceNet?

    You will only have access to VINs in your fleet as applied thru your purchasing dealer.

    I can walk you thru how to look them up if you already have access. But so should the dealer that set up your Ecat login.
