    I have a western unimount, low beam plow lights work fine but when I switch to high beams only parking lights. When I unplug 9-pin harness vehicle high beams work fine. Any suggestions on what could be wrong? Relays?

    I have a 4 relay system with a plug in harness for non-DRL. Which relay should I be checking, vehicle or plow light high beams?

    Thanks for the responses. I will be checking it out in the morning. Are the relays all the same and interchangable?

    I took advantage of the nice weather today to fix my lighting problem. It did end up being the plow high beam relay. Thanks for your help!
