I am wondering if anyone can let me know what each wire does on the fuel pump. If i recall correctly there are 4 of them. I found a wire diagram but suck with electronics.

It seems like itd be the 4 wires in the upper right corner, but for some reason i swear one was pure black. I will have to double check when I get home. If that diagram is correct i would use c1 as my ground, but would i use c5 or c1 on the new fuel pumps power wire. My new fuel pump has a ground and positive only.

 

At the fuel pump module connector:
Pin 1: Black, ground.
Pin 2: Dark Blue, Fuel Level Signal.
Pin 3: Dark Blue/Yellow, Fuel Level Sensor Ground. (Electronically grounds on one of the TIPM circuit boards)
Pin 4: Dark Blue/Orange, Fused Fuel Pump Motor Power
