Resurrecting this thread to add more info. I'm finally re-wiring my truck. Ray's wiring diagram is very helpful but I also sorted out the fuel related wiring from my old harness to add some pictures. Even though it wasn't originally working on my truck, as far as I know this wiring and these connectors are factory.

First is the switch and the plug going into it. Pink w/black stripe goes off presumably to my old fuse box. Showing the connector on it for reference - not sure it was original.
