  • Looking for 98+ wiring diagrams

    Anybody know where I can find wiring diagrams for 98+ LS1 car's? I already have the PCM pinouts but what I really need to see is the wiring asscoiated to the A/C circuit as I am retrofitting my car with a system.

    what year?
    97-98 are not the same as 99

      Yep. Need to know what year harness. I'm sure 1BadAir can help you, but if not I can get you what you need too.

        I have a set of 1999 factory service manuals, they probably have wiring diagrams in there.
        When in doubt, Whip it out !

          I don't care...I know the PCM's were different, I already have the pin-outs for my 99 PCM. I just need to see how the A/C system used the pressure switches and clutch relay as it relates to the wiring. I have a pretty good idea how it needs to be but i just want to see how GM did it.

          Yes, a factory service diagram is exactly what I'm looking for and 99 will work perfect. The GM manuals break it down by system and that's what I want to see. Anyway you could scan them and .pdf them to me?
