Thanks for the info, LockDoc. The black wire really had me stumped and I couldn't follow the wiring diagram. Still trying to get use to the fact they use the ground side to break the power rather than the power side on these trucks. Thought they would have used white or green to signify it was ground and black or red for power.
I'll retest the pump and if it works I get to install my second piece in the cab!! The first piece was the dome light and running that wire.
