Thanx for all the info this far!!
OK, this is a little uclear for me too. If the ECU supplies the ground for the BCS (orange wire to pin 105) and the FPS (white wire to pin 57), then why do we ground the red wires of the two solenoids? I believe this is what 92GS-T'd was asking.
Wouldn't it make sense to power these wires like the white wire going into the injector resistor pack?
Also, did anyone else connect the IRP's white wire to the Thick Red wire in the wiring harness on the intake manifold w/good results?
