    I have a western unimount that I hooked up for the first time this year and no plow lights, I looked at the troubleshooting guide just to confuse me more:dizzy: I noticed when trying to resolve the problem the truck lights a couple times wouldn't work at all only on high beams. Seams to me a connection issue. If you guys have any ideas where to begin please let me know. Any help would be appreciated. Thanks

    Need to get your test light out.

    With the lights on you should have power on the brown wire coming into the relays. with the plow unplugged you shold have power on the yellow for low and green for high, this is power in from the truck harness. Should have power on orange for low and red for high, this is going to the truck lights.
    With the plow plugged in you should have power on black for low and white for high going out to the plow and black orange is ground.

    Also, the power plug for the plow runs the plow headlights. So if you only have the signal plug connected, it will shut off the truck headlights, but the plow headlights won't work either. That is only for the headlights though, the turn signals and such should work together.
