Does someone have a pinout for this relay, or know which wires go where. Doing an LS swap and i know the LS pcm will supply +12v signal for the relay.
I would like to use the existing square body relay and TBI fuel system and just replace the pump in the sending unit with one from a ~97 3500 which I read will be a direct fit and correct psi.
I would like to keep the hard lines and just adapt to AN somewhere by the firewall, near the motor. The lines at the sending unit were approx 12” of rubber hose that were hose clamped on both ends. I don’t believe this to be correct? Maybe adapt to AN here as well…
