Fuel Pump Relay ouput

Postby Crazyced » Thu Oct 20, 2016 1:49 am

Quick check, the pin 18 on the S14 SR20 ECU (69F00), the Fuel Pump Relay output. It is pulling to ground? Meaning you hook one side of the relay to some switched 12v and the other side to this ECU pin?

I guess I should just ask, are most output drivers on this ECU (except #25 - WGA) pulling to ground?

Yes fuel pump output pulls to ground (other side of fuel pump relay is 12V)
