    Hey guys and girls i have a MM1. It use to be on a 98 ram with DRL.... Needless to say the plow outlasted the truck. So i removed the wiring harness and put it into my 01 ram. With out DRL. And now i have no headlights with out the plow plugged in. But when i have the plow plugged in i have high beams on with my light switch turned off and there stuck on even when the trucks off and the light switch turned off.

    I had almost a similar problem about 4 years ago with the 98 ram But it turned out the DRL box went bad was a simple disconnect fixed that problem but the 01 does not have the DRL box to unplug.....

    Any Help :'(
