    just bought a 03 Western Ultra mount Pro 7'6" with updated harness w/ISO box that came off of a 06 Chevy 1500 silverado and I am putting it on a 01 Chevy 1500 silverado

    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

    My ? is what are the headlight wire harness #'s that I need to make this work on my 01 & can I still use the Isolation box.

    I contacted Western & the email told me that I no longer need the 06 headlight harnesses # 2635 * & 26352 * & to buy the 26360-1 & 2636-1 Which my dealer told me were adapters at $100 each:cry: the counter guy may not no what he is talking about & they may be the actual harness that I need I just want to confirm this so I can find the Harnesses on ebay

    Can someone look on there I think 99-02 1500 with Ultramount & ISO box & tell me what the headlight harness #'s are

    Here is what I have:
    Isolation box 27779
    port 4 harness 26351 *
    port 3 harness 26352 *
    port 2 harness 26357
    port 1 harness 26345

    I think I could also just get the whole harness kit for the 01 at $250 part # 8437-1 & sell what I have

    All I had to do was tell my parts guy that I needed whatever it took to make my 04 set up work on my 02.

    He came back 5 mins later after thumbing through his book with two headlight harnesses.

    I'd tell you what they are but it might be different on a 3/4 ton.

    Your parts guy too lazy to look it up and try and make a sale?
