It's time again for name that plug! I'm re doing my headgasket and have it all together. While I was in there doing everything I found this little guy down below the battery tray but it is neither of the washer fluid plugs. Can anyone help me out and tell me where it's supposed to connect to and what its function is. It has been jumped with a little wire since I bought it.

Hey...I'll try to help you BUT...I'm going to assume it's a 22re but that's only because you don't say what engine or what year....need more details.

Yeah sorry it's a 95 4wd with a 22RE

resembles what is plugged into my washer pump.

wow, crap, that's blurry big like that

I definitely checked those. Since it's a 4Runner it has two one front and one for the back but it's baffling since both are already plugged it. It looks like a non OEM radiator could it be some coolant temperature sensor that used to be on the radiator?

sorry couldn't help you more than that.

95 and my 92 should be the same i would think....no such other plug around there that I see.

what do you mean, "it was jumped" ??

melicha8

It was a female connector and it had a wire inserted on one side bending over and going into the other just as one would do when checking diagnostic trouble codes

Can anybody take a look in their 4runner and see where this leads?

Looks like it's close enough to the A/C parts that it could be related to that. I know I've "tested" my compressor on other cars by jumping the connector for the A/C pressure switch (turns off the system when too much freon leaks out). Maybe this could have been done by the previous owner and just never hooked back up. Does your A/C work? Is there are switch port in the A/C line nearby? I guess it is usually near the receiver/dryer.
