LS Swap. Need to figure out power for pumps.
I am having trouble seeing which wire/s I need to supply power to run the pumps. Four wires coming from the pumps. Two into the fuse block and two into the fire wall. Anyone know for sure before I start pulling wires and testing? 1987 Chevrolet V30- JSTEWY
