    I just installed my v-plow on my 2012 3500 GMC, the plow was on a 2008 2500 Chevy, according to the fisher website all wiring would change over. I hooked everything up and have checked all fuses and have power on the wires that hook to the plow, but cannot get the controller to power on and the truck lights are not shutting off, the plow lights are coming on but are barely visible. Could the isolation module be bad?

    something is incorrectly wired, if the plow lights are not turning on then you are not completing the circuit

    The plow lights are turning on, but very dim. The truck lights aren't shutting off. Going to re-check all the wiring.

    Check the connections on the headlights and isolation module.
