    Plow low beams stay on when truck is off- plow park lights are off though??? What would cause this? Relays are newer. When truck is on and I turn on plow lights, truck lights and plow lights are both on? Truck sat all summer and was fine last winter.

    9pin western unimount two plug. 4 relays.

    bad realy or corrosion

    If you unplug the plow connector then plug it back in, do the plow lights come on, or do you have to turn the lights switch on then they stay on?

    They are on as soon as you plug in the connector. The relays are new. The parking lights on the plow work properly. I tightened all the wire connections on the wires that connect to the relays and use dialect. grease. I cleaned the two plow to truck connectors.

    Maybe I will just install a toggle for the plow lows?....

    Something is wired wrong, pwr to the relay cause you gnd the relays by the plow connector.

    How new are the relays... about as new as when the problem started??

    I think dieselss hit it, sounds like wires are not correct

    Are they the correct relays as well?? Do they have the 87a circuit?
