plow switch over

    HELLO ALL and Merry Christmas
    I am new here and hope I'm asking this in the right section.
    I had my Fisher v plow on an 02 duramax Silverado.
    Just changed it over to an 04 Sierra Duramax.
    Everything went well and is working correctly...I think.. except the lights.
    On my old truck, when I plugged in the light harness, the truck lights automatically switched to the plow. Now I cannot get a a light signal to the lights, I guess it didn't help that I tried to switch to newer lights.
    Anyone know if the 02 wiring harness is the same for the 04 ?
    Should I not be able to get my tester to read light on the wires when lights are on?
    I'm puzzled because the high beams stay on when the harness is plugged in.
    Any insight would be appreciated.

    For a quick answer. Try fishers quick match. Input both trks and see if the wiring harnesses ate the same

    wiring from 02 duramax to 04 duramax

    Thank you for the replies. I will work on getting the light harness for the 04.
    One more quick question. my plow is functioning well. except for the left and right angle. when the blade is stright, i should be able to make a complete left and right angle but currently have to use the wing button to complete r & l angles. not locking. any ideas or is the wiring harness completely different from 02 to 04?
    many thanks again.
