    I got 87301-3467 for cab harness, is this correct? I also called WS and they gave me a different number (wws 87208-3436) but they are no where to be found and I need the actual entire harness like in the picture. I might just dump this truck on the scrap yard soon :(

    Why?...I gave you the exact schematic. You can very easily verify which pin in the jumper goes to which plug.

    Not even sure what your symptom or problem is. And trying to slam dunk an entire harness will cause more issues than solve them.

    Brother,
    The shop that has the truck, for some reason the harnes started to catch on fire after replacing the ecm. The ecm supposedly was bad, it was sent back. Shop got a new one but the plug and the initial part of the harness is burned, so we need a new harness to replace the burned one

    I was going to say if it was a thermal event...aka fire. In that case, then that shop better be replacing all of that. This shop sounds partly responsible.

    I never heard of an ECM causing a fire--especially when the ECM has a 20 amp fused supply. If it was me, I'd be pretty furious.
