    A/C Wiring Diagram

    I got sick of juggling between the VA manual wiring/another VA wiring diagram/looking at car wiring and still not being sure what's going on, so I sat down and drew this out.

    Sharing so other can use it (as well as tell me where I did something stupid).

    I have a crate engine, so I wired the fans to turn on when the engine controller wants them to OR when the A/C wants them to.
    I added a fan relay because I wasn't sure if the VA switch was rated for the amp draw of the fans. I figured it was, but relays are cheap.
