    I bought a used Boss v-plow. I have the wiring figured out except for the fifth relay.

    I have a 13 pin harness.
    I have a bank of four relays.
    There is a fifth seperate relay. It has a red wire that goes to constant power, it has an inline fuse. There is a purple wire that has a bullet plug end on it. There is a purple wire that is cut. There is a white wire that is cut. Could this relay have something to do with the headlights? Dual burn? How do I wire it up?

    I am wondering if this may be a turn signal relay. Anyone know for sure?

    What was the wiring removed from?

    That appears to be part of a MSC9003 head light adapted kit that is used on 2007 and up GMC/Chevy's with HB2 & H11 headlights...
    It is for the turn signals...
    Save it in case you want to set your plow up to have Dual Burn headlights...

    :rolleyes: John...

    The wiring was removed from a 2007 Silverado, going into a 2005 Silverado.

    Thanks Garagekeeper.
