I'm running a haltech and I can't find the wire for the oil pressure sender. I know the plug came off so it's just a single bare wire. It's too dark and late for me to dig through under the hood looking for it but before I go back tomorrow, is it part of the ignition harness that doesn't get removed or is it part of the emissions harness that gets removed? If the second, how do you guys wire it up after doing the swap?

 

The oil pressure sender wire is in the engine harness, not the emissions harness, so it does not get removed. It's in the same bunch of wires as the oil level sender and sub-zero oil temp switch. Check out the harness schematics at the back of the FSM wiring diagrams.

 

yeah but they're ahrd to look at, I know there are guys like you that know this off hand NZ :-P Thanks for the info

 

The harness schematics are really simple, trust me. It's just the plugs with lines representing the loom inbetween.
