[QUOTE="gouldbri, post: 13139195, member: 98833"] I tried to wire my return style fuel system the way Malcolm suggests and I could not get it to work at all. I used to power the relays from the green/yellow wire and the everything worked fine but it was annoying to have the pumps run all the time. I have the Lethal 1200RWHP return style fuel system with their wiring harness. I reconnected the green/yellow wire as it was stock and used the brown/pink wire to trigger the relays (blue wire on lethal harness) from the connector side of the fpdm. I then used the red/black wire from the connector side of the fpdm to ground the relays (black wires on lethal harness). with key on I get power out of the brown/pink from the connector of the fpdm but it seems the red/black from the fpdm connector side is not grounding the relays. I was able to get the pumps to run all the time by just grounding the relays to the chassis and using the brown/pink to trigger the relays but as Malcolm said the pumps run all the time. Is there something I have wrong here? any help would be appreciated. Thanks [/QUOTE]
