I lost a batch of disassembly pictures this wire originates from harness in the valley - its yellow /green female spade terminal and has a mounting. Hopefully this looks familiar so I can work on installing new alternator instead of searching

 

I cannot be certain without a wiring diagram and assuming the wire is long enough; that looks like the wire that goes to the dash temp guage sender on A bank front water manifold. If so, that P clip holds it in place where it goes round the end of the cam cover.

 

Not sure if this helps - for scale it would not reach the temperature sensor ( and I already have a connection to it) - the natural orientation looks like it would go to the left or up - but it sure feels like everything is all connected up top? (Both mictoswitches and coil all have connections made) I am baffled I guess I keep standing here with a beer and eventually I’ll see it

 

Well whatever it does, it didn't impact the engine starting and idling/reving smoother than I've experienced since owning the car (<1 year)
I've had engine/transmission out since Oct. Last night was its first startup since. Cycled the key a few times to build fuel pressure, tighten down a few fuel connections I forgot clean up, cycle again, confirm no leaks, turn the key and she fires and purrs immediately - I love this engine!

I did remove/delete air pump (the air rail was clogged and it disintegrated on removal). I've gone through the box 'o' parts I am storing for who knows why.. many times I don't see any single male spade connectors...I'll zip tie it to the rest of the harness on the stablizer bar and move on to other tasks.
