Western / Dodge RAM light wiring issues

    I just installed a used western 7.5 unimount on a 99 dodge ram 2500. The parking lights & turn signals work fine. (truck and plow). No beams on plow at all (high or low). Truck low beams DO go off when plow is connected. I hear the relays clicking when I connect the plow.

    Is it possible I have the wrong wiring harness? Everything pluged in OK (headlights, turn signals). I believe my dodge sends 12v to the common, and grounds the appropriate beam (low or high). Anyone have experience with this setup? There are 2 relays - 1 for low and 1 for high beams.

    All connections are good.

    Do you know what truck the harness came off of?

    Check you relays, its a common problem with the westerns.

    You have the wrong harness, you should have 4 relays with a power harness to the relays.

    What headlights do you have, HB1 or HB5?
