Plow lights will not switch on, none of them!

    when i go to plug in my plow lights, last year they switched from truck lights to plow lights when they were connected up

    this year when i plug them in, the truck lights stay on in both high and low beam

    i sandblasted the connections on the 13 plug harness and still didnt make a difference

    also replaced the 2 little relays and checked the wiring harness colors, all the wires match up to where theyre supposed to be plugged in

    any other ideas? is there supposed to be a switch in the cab to manually switch the lights over? no plow lights work...not even marker lights or turn signals

    thanks!! its a unimount setup

    I know theres no switch, its all 100% automatic---is yours the 12 pin or 9 pin (fairly certain theres no 13) I have 9 and there is 4 relays.
