    I just bought a 03 Western Ultra mount Pro 7'6" with updated harness that came off of a 06 Chevy 1500 silverado and I am putting it on a 01 Chevy 1500 silverado .Will the wiring harness work:dizzy:

    The harness has a 11 pin & a 3 pin on truck & plow sides & it does have a isolation module box ,And both truck have the day time running lights & there is a wire for that on the harness

    I guess I could just try it but would rather have confermation that I am not waisting my time
    Is there a # to call at Western as my local dealer said he would have to look it all up.:salute:

    I do have part #'s

    port 4 harness 26351
    port 3 harness 26352
    port 2 harness 26357
