Boss plow headlight issues

    Hi guys, first time poster but have browsed for months. We installed a boss rt3 8'2" v plow on my brothers '04 silverado 2500hd and it keeps blowing fuses when we try the brights. Weather it's the truck side or plow we have no brights and the fuses pop when we try. Also, the truck and plow headlights are both on when we have switch to plow. When truck side is selected everything works except high beams.

    Wiring was originally off. Ford I believe and we got new headlight harnesses (msc04601) for 04 chevy. Wiring has 4 relays. Plow is smart hitch 2 if that makes any difference.

    Appreciate any help you can offer.

    Tried standard and reverse orientation to no avail. Also tried swapping relays to see if had a bad one maybe???

    You have at least one of the adapters plugged in backward. They'll go one of two ways but only one way is correct for the model year you're working on. Which all need to be on the "A' side.

    I'll assure you it's still an installer issue. Either you're not reading the plugs orientation correctly or you have the option plug still plugged in on the reverse orientation instead of the standard orientation. Or you're connecting the adapter to themselves (eventually looped). Because they're the only things that'll blow fuses and/or cause both the truck and plow lamps to be on together.

    :nod::nod: Mike nailed it right on the head. You are just wasting your time if you look for any other issue. Just go back to the starting point and do it all again confirming you have the proper orientation.:waving:

    Double, triple checked that all connections are on "A" and also standard orientation. Still popping hi beam fuses when flip them to brights. Relay or something maybe?

    Does it pop hi beam fuses without the plow plugged in? If it does, then one of your new headlight adapters was pinned incorrectly from the factory. Don't see it very often but I have seen it.

    The fact that the truck and plow lights are on at the same time says it's a configuration issue. Mis-pinned etc.
