Has anyone got a drawing or description of how to wire up the fuel gauge on a AD? I bought a repo fuel sender, and put the voltage reducer on the center terminal on the sender. It looks to me like there is another electrical connection on top of the send (small stud with a nut on top) I can't remember how to wire the gauge or the sender now that I have let the whole thing sit for a year or so.

FYI, I am rewiring the whole truck with a very basic fuseblock/wiring harness.
