Oil pressure gauge and efi harness

[Desert Thrasher]

I installed a new Auto Meter electric oil pressure gauge and I want to know if I hook up the sender wire to the wire from the RJM harness or just straight to the gauge? Thanks.

Since I don't have an RJM harness, I'd suggest figuring out where that oil psi wire goes to & from in the RJM harness. If it's open on both ends, just tap into both ends of it and then you don't have to run a loose wire for the sending unit.

As far as I know....OBD1 does not monitor oil psi so it's probably free standing.

should work its just a wire, you will want to use the sending unit that came with the gauge.

I chased the wire in the harness and it is separate from the efi part so I hooked it up and everything works good. Just me over thinking simple things again. Thanks.

Yeah, Ford computer don't care about oil PSI. Run what came with the gauge.
