Re: 4agze wiring help!!!! PLEASE	Mon, 10 February 2003 20:53

I was going off memory as I haven't wired a MAP 4AGZE for some time. Most Toyota's use a circuit opening relay and a fuel pump relay. This is a bit confusing as the COR is actually the one that supplies power to the pump while the FPR simply brings a resistor in or out to vary pump voltage depending on rpm and other load factors. The FPR is not required if you are using an external pump but can prematurally wear out a factory in-tank pump if not used. If your 4AGZE does use BOTH relays (consult your wiring diagram or pinout) then the COR signal wire (green usually) goes to pin FC (or labled something similar) on the ecu. The FPR signal wire goes to pin FPR on the ecu. If I think of it tonight I'll look at my diagrams. [Updated on: Mon, 10 February 2003 20:55] [Report message to a moderator]
