    Have you tried another plow to see if its the truck or the plow?It could be a number of things.It could be the connector on the truck.It is either a 9 pin or an 11 pin.This connector can be fixed one of two ways.Either buy the repair end and hope it works,or replace the whole harness.My plow had no lights or the controller didn't light up and the plow wouldn't move.The wires inside short together and won't work.I replaced the harness which runs from the truck,directly to the isolation module.I think its the second port on my 4 port module.Let me know if this helps.

    Did you find that out before I told you? Did you end up buying the repair end or the whole harness?
