    I believe pluging in the plow connector energizes a relay that grounds the trucks headlight circuit and feeds the plow circuit- the relay could be bad. If it''s not the ISO module system (the newer 3 plug system) it should be easy to trace back- I'll trace mine back as soon as I get a chance (and it stops raining)

    lost plow lights

    try checking the Bosch relays that the plow lights are spliced into, these regularly fail on my vehicle to the point that I carry atleast one replaement...also check the positioning on the soleniods and move them up from under the battery tray (that's were most installers like to hide them) to a place were they are more protected from weather. PS there should be two solenoids one for low and one for high beams, also check wiring connectors (the 1/4" tabs for broken wires) and obviously replace
