    just bought a MM2 3 plug blade and need to get the truck side wiring for a 2000 GMC sierra. I found someone selling a 4 port isolation module with the headlight wiring for my truck but dont know the main wiring part number or price of it to see if its worth it.

    If you have the newer body style 2000 with the HB-3/HB-4 headlights you need either the yellow or green label Isolation module (green label is the updated replacement for the original yellow label) headlight harnesses are 26360 (Long), 26361 (short) and 26357 is the 11 pin universal harness. The whole lighting kit, harnesses and Isolation module carries a part # of 8437-1, remember this is for the headlights only and does not include the control harness, controller, battery cables and solenoid.
    If you have the older body style 2000 it's a different story.
    What are the part numbers off the wiring for sale? Is it the whole truck side electrical?

    I do have the newer body style. For sale is only the module and the 2 headlight harnesses,looks like a yellow module from the picture. Havent gone to see the parts yet, was told it is off a 2004 gmc pick up. I wanted to see what the missing parts would cost before I go.

    Headlight harnesses from an 04 will not work for your vehicle unless they are reconfigured, (99 to 02 body styles have a negative common system). The isolation module an 11 pin harness are ok.

    if he took it off an 03-06 chevy then the two harnesses that go to the lights will be wrong. the plugs are the same but the colors are swapped around on all of them.
    as for the other parts you would need, they would be the 26345 main harness and the 63411 battery cable that plugs in (you can get those a little cheaper as a 28055 kit), then that would just leave the solenoid and little battery cable.
    so, unless that guy is selling what he has for next to nothing it won't do you too much good.
