How to Rewire your Custom Car is a step by step guide on how I wire a project that has absolutely wire harness existing in the vehicle. I would say that this is starting from scratch, but it is actually at itch (what comes before the scratch)


Using a Painless Wiring 21 circuit wiring harness, along with a Switch Pros solid state controller I add all the required circuits along with heat and AC to a the classic Willys Wagon.
