Please help with unknown wire connector
I have a 1999 4Runner that I've just finished replacing the motor, it's a 5vz-fe. I have all of the wire connections routed to their proper locations but can't figure out 1.
It's routed on the passenger side by the A/C compressor and P/S pump and it's being split from the camshaft position sensor wire loom. The A/C compressor only has a one pin connector which is connected as is the camshaft position sensor. So there's only this 1 connector left. I've looked at many diagrams which lead me to assume that this would connect to the p/s pressure switch but there isn't any connectors on the p/s pump/bracket/body. It's just a 1 pin connector and I can't verify it's color at the moment. Can anyone run out and take a look for me? Thanks!

theres a connector that comes out from behind the riming belt cover. that one maybe? there's another that runs down by the oil pan too.

The oil pan is the starter wires and is not directly part of the engine harness, it connects straight to the battery. The timing belt connector is for the camshaft position sensor which is already connected.

ummmmmmm is it possible the donor vehicle didn't have that particular feature? on my harness (97) coming from the top of the timing cover is only the two connectors. one for the ac and the cam position sensor. maybe that was part of the mid gen upgrades...

I'm using the same engine harness that originally came in the vehicle. I only replaced the long block. So I'm reusing All of the pumps and sensors from the original. I can't recall if there was a sensor connected to this plug or what....

Pictures would help.... That being said I was just in that "area" of my 4Runner recently. What you describe sounds like the power steering pressure switch. The A/C wire, I believe, has a gray plug. The p/s wire should have a black plug thats has a kind of "D" shape to it. Hope this helps

I can look when it's light out tommorow if you are still stuck on this. When you stretch out the wire are there any likely candidates in the area? What is the size and shape of the plug?

The connector goes to a pressure switch for the power steering. Its on the PS line, NOT on the pump/brackets. I assume you used the lines/pump/harness from your 99 4Runner?
There should be a switch like this on your pressure line on the back side of the pressure line, at the pump:

The starter plug could only connect to the starter. The lead coming from the starter itself is only a few inches, before it disappears into the starter harness. It isn't even remotely close to the Cam position sensor wire, and in fact its a completely different subharness

On another note, I started to fill the block with coolant through the top coolant hose and the coolant leaked from the passenger side. I took a look and noticed this was in fact a bleeder valve with a missing top bolt to stop it. Lucky for me I still have the old block sitting here. But man, getting that bolt in there with the engine mounted and the accessories attached was such a huge pain, not in the "A," but pain on my hands LOL! In the end, I was able to attach the bolt to stop the bleeding, refilled with coolant and no more leaks. She's almost all ready to go!
Thanks for your input and suggestions guys/gals. I really appreciate you taking the time to help me out. Cheers!

I'll have to look for that PS pressure switch on my rig as I cannot remember seeing it and I've had the rig for 16 years.
