Here's the wiring diagram with the wire colors. The connector for the pump module was the hardest one to find. I'm including a number of other connectors and relays in case you need them. The pump module connector is at the top of the last drawing.
The 5.9 uses a simple 4 wire system on the pump. The Dark Green w/black stripe on pin 4 is power from the relay, The Black wire on pin 1 is the ground. Then for the level sender you have Dark Blue w/white as the power from the PCM to the sender on pin 3 and the return to the PCM is the Black w/light blue wire on pin 2.
