So I have a stm rewire kit and I know what the wires are for the relay, but I don't know what colors mean what on the fuel pump side.
STM Wires-
#30BLUE Feed wire --->battery to relay.
#87YEL 12v pump wire(Pump side) --->what color does this one go to on the car?
#86BLK 12v pump wire(Car Side) ---> what color does this one go to on the car?
#85WH Ground -->grounds to frame
 
GVR4 should be the exact same as a 1G. So the black wire with a white stripe is your power wire. Cut it and connect the harness side of the wire to pin 86, and the connector side to pin 87.

86 is the power for the relay to work
85 is its ground so that the relay functions
30 and 87 are the switching poles of the relay for your pump to get power from the battery to the pump. :)
