    98 2500 just installed night saberlights and relays. The turn and park lights works fine. But with the plow lights connected both hi and low beam light on the plow and truck (depending if I have the relays on). If I disconnect the plow lights I dont have the truck headlights at all. The truck headlights are dual bulbs. I know the wiring is correct.

    "I know the wiring is correct"

    Check your grounds.

    The only ground is the relay. The lights are grounded thru the harness. I saw some where that the lights might need to be grounded separate not thru the common wire

    Are you talking about the Meyer headlight module's?
    There's a switch to control the plow lights correct?

    Some Meyer modules have fuses inside them.

    Yes these do. Ahhh so is there a fuse for both the truck lights and plow lights?

    I would check the module fuses and the truck's headlight fuses. Have seen bad modules blow the truck fuses.

    So your thinking the ground wire is stopping the truck headlights from working also
