If you begin at the starter, as you follow that part of the harness up, about 1/3 or 1/2 of the way up you find a small black connector.
This is one of the connectors that in my haste I didn't label. I'm a little unsure what it is or where it connects. It appears to be similar to a ground that you would plug into a grounding "tab" as is the case in other areas of the car, but can someone help me out? Even better if you can take a picture of where it connects I'd greatly appreciate it. Thanks

i'm pretty sure it goes to you oil pressure unit, a black rubber thing with a little tab coming out of it.

 

I think its the one that clips on the male connector below the oil filter. maybe?

 

That's what I thought, plugged it in there, but it seemed the wire was pulled pretty tight... I just wasn't sure. Thanks guys.

 

Yeah, that oil wire IS a bit short...

 

The oil pressure sending unit wire(connector) comes down from the engine harness across the top rear of the engine.

It is not part of the harness that connects to the starter!

 

The wire to the oil pressure sender is the one you type about ,the wire is gray and red .The wire that comes across the engine and down goes to the water temp gage sender, the wire color is yellow and white .

 

Well, in my car, wherein I JUST re-wrapped the entire starter harness as part of my battery relocation, I had to be cautious as to which way I broke out the oil pressure sender wire, as it was too short if it brok out pointing down. So I guess on MY car, the oil wire is on the starter harness...
