I'm running an electric fuel pump, with relay, and there is no mechanical pump installed (It's blocked off) on the 56' C3 12V PW. My oil pressure switch has three spade connectors (I- ignition switch, S- to starter wire, and P- to relay). Question is, where does the "S" wire get connected to, seeing how we have a mechanical starter? I believe that wire provides momentary power to fuel pump during initial start-up. Should I leave that wire disconnected, or maybe install a momentary switch on the dash? I see in the archives that Vaughn says the truck builds oil pressure quick enough that the switch may not be needed. Any thought, or advice, on wiring up the fuel pump? Thanks.
