I just put another motor on this car. It's not an AWD, I can't seem to find the connector going to the hpfp on the passenger side which is right on to of the valve cover. Can you find out for me which harness patch does it come out from? All coils and injector wires are in but no separate wire is found coming from there. It's a 2 wire connector. You will see where it plugs into the pump, grey connector on pump.

Hi,

My wiring schematics aren't set up in a way to know where the harness would be located.
However, it should be a 2-wire connector and if I recall, the wires are red and white. Also, they should travel to the HPFP from under it. Have you checked closely under the pump?

Let me know.
