Mystery Plug

I feel like a dumb **** on this one. IN the attached picture, I have circled a plug I can't find a match to. Any ideas?

I seem to have lots of mystery plugs in my car that go to nothing.

That looks like one of the plugs that mate with the ACV on the left side of the block. Those are part of the same spiderweb of a wire harness that snakes over the top of the rats nest.

It's for the temp switch that operates the optional auxiliary fan in front of the radiator. It sits on the back of the water pump next to the ECU's thermosensor.

If you don't have the fan, you don't have the temp switch, hence the spare plug.


Goddamn n00bs chocking teh bandwith.
