Going to re-hard wire my DW 300 FUEL PUMP. my question is which pin should I use from the ecu for a turn on signal. Pin 22...or pin 39. The EVO pump uses three relays with a resistor. At low demand the pump gets 10 volts, jumps up to 13 volts on high demands. Wiring diagram says pin #22 is the fuel pump relay, pin#39 says It's the relay for high demand. Which one should I use for a signal to my new relay? Has anyone done this before? My guess is pin #39.

Revive this!! lol I've been searching for hours, is there a simple way to utilize the factory ecu, Hi/Lo pump control for the hard wire of the pump (or pumps) as I'm looking to hard wire the TWO DW 301's...


Thanks guys!!
