Engine wiring harness ID assistance 5VZ

[BuffaloBass]

Folks, i hope someone can shed light on this..... i have one "unassigned" connector on the 5VZ harness. ( Am replacing the engine with a reman.) I labled it "temp sensor" , but its partner was labeled " intake" and it is clearly for the AC compressor. ( the oily gunk iis a dead giveaway)

This is the leg that has the cam timing sensor and then two more branches. As i mislabeled them, and there is no clear place to plug that D shaped connector into, I am lost. The circular connector clearly goes to the AC pump. So its D shaped partner ought be nearby, and there is nothing to plug it into.

I see no other sockets near there ALTHOUGH there is a brass plug in the water jacket yet i cant see having yet a third temp sensor there. I wish i had kept the original engine core a bit longer for matching stuff like this.

Anyway, here are the two ends; the D shaped end is the one I cannot figure out. The other circular goes to the AC compressor. That D shaped connector that branches out from the AC connector? ANY THOUGHTS?

One's for power steering idle up the other for ac compressor clutch.

Power steering has a plug? Well, its up on the bench now for hose R&R, I guess I should have waited a day to ask!

I didnt see any plug on the PS pump when i looked it over and don't recall one, but it's so gunky it could easily be hiding. Yet, I cant recall EVER plugging ANYTHING into a PS pump of this vintage, other than hoses. Makes me think i would have recalled unplugging it.

" a picture is worth a thousand words". I have to remember that!

To be more clear, this is on the bottom side of the pump, on '99+ MY 5VZs. Earlier ('96-'98) use a vacuum switch for the same PS idle-up function.

Thank you Charlie! What I have is an electrical prong sticking out of the high pressure feed fitting, not on the pump itself. Boy, i missed that!

I remember when I did my frame swap it took me a good while to find where to plug that baby back in.

..and i buggered up the switch, NAPA had one in stock. ECH PS310. Many PS pumps must have these. Was only going to replace the o-ring. Oh well! THNX ALL!
