Found this plug dangling while I was swapping out my transmission the other day. 1987 4runner SR5 , runs fine but Im sure that its supposed to be plugged in somewhere. Its hanging under the intake on the passenger side. I looked around but couldn't find any other open plugs.

My guess is cold start fuel injector. Will only affect starting in colder weather although I would plug it back in.

Can you take a picture of where it goes? Truck has fired right up when the temp was in the teens

I have a couple of those boots, one was in backseat storage in my '91 and another was on my '92 parts truck. I think often they get removed and lost or tossed.

I think is for the idle air control valve, it is just below the intake manifold.

The one on post #12 is the one you're looking for in your '87.

If you find it doesn't go here to the IACV then it's an unused connector for an auto trans or something else. I can't remember what it was for. I've had two other 4Runners that had the same unused light blue connector dangling.
