Yesterday I removed the wires from the relay connector to make it easier to run the wiring harness down the side of the Fuel tank, then I was going to quickly reconnect the wires/terminals into the connector. Anyway that didn't happen, and now I need to know what color wire goes to each of the four pins on the relay.

BTW this is the Upgrade Wiring Harness (# F99-FPWH Wiring), for a 99+ LS1 F-Body.

Thanks!

pin 85 is the black ground wire (chassis ground)
pin 87 is the red wire running to the pump connector
pin 86 is the gray wire running to the pump connector
pin 30 is the red wire coming from the 20a fuze.

hope that helps
