C5 fuel pump wiring

04-24-2008, 12:41 pm

Ok,
Can someone tell me what the 4 wires in the connector to the fule pumnp on the drivers side go to? There are 4 prongs, which to are 12 volts from the pump relay, which is +12, -12, and I assume the other 2 are the sender. I have no pressure at the rail...the relay is good as well as the fuse 13. I was going to attach 12 volts directly to the fuel pump, but need the two wires identified.
