'86 22RE. It looked like rats had gotten to the wires to this connector, it's in bad shape. It plugs into the lower intake manifold, towards the front (front meaning near cylinder intake port #1)..can someone tell me A: what is the function of this, and B: where would I find another connector?

 

Here is another pic of it.

 

It's green right?

Coolant temp sender plug. To the right of the intake as you face the motor. It's important to have for proper ECU/emissions during engine warmup. There is a brown plug coming off the same loom, which connects to teh sender next to it.

 

my image doesn't seem to work...try this link:

It's not the coolant unit, I've already replaced that one because it was rotten literally. LOL. If you are standing on the pass side, reach under the upper manifold, heading towards the engine, it's in there. It's attached to the lower manifold its not any of the sensors you can see from the front.

 

Is it blue? I couldn't tell on my screen. If blue, it plugs into the back of the idle air control valve. Comes off the wiring harness that is sandwiched between upper and lower manifolds.

 

It looks like it maybe used to be blue..it's a real dark hunter green color. I'll check on iac valve connectors real quick and see.

 

can you share some photos of those areas of your engine so we can get an idea if you're missing anythin?

 

Yeah man ill take some when I get home a little later.

 

Ok man, it's the IAC connector. I took it off and there it was. I got some female spades, put them into the connectors inside of the iac, then epoxied them in. Good to go!!
