Wiring Problem with towing

[bigjake6]

Have you checked the factory (female) tow plug on the truck for appropriate voltage as you turn on the lights, blinkers, brakes, etc? If this is ok, then I would think the problem lies in the male plug of the magnetic light set. Have you used the magnetic light set before with success? Or has it set outside to the point that there is debris or rust in the plug? Are the wires in the male plug wired incorrectly? What about bad grounds. It seems like everytime I have an electrical issue with a situation where I am saying to myself, "this worked fine last month, why won't it work now" it tends to be a bad ground.
