What do I hook my RJM EFI oil pressure wire to since I am running a mechanical oil pressure gauge?

Since you are using a mechanical oil pressure gauge, you can leave the wire on the RJM harness disconnected. Leaving this wiring disconnected will not effect the EFI system, it is just a wire that connects that electric sending unit to the gauge. I am just taking this from memory of rebuilding/modifying a mustang for my bronco and also from the Old Ford Racing Harness Manual which has wiring information.
