I have 2 plugs that for the life of me i don't know where they go/what they are. They both come from a harness from the ecu box and split off near the driver headlight.
I hope that one of these will solve my A/C problem. no clutch or compressor kicking on when I turn the A/C on.



1st plug. 4 pins.

Then the second plug travels beside the radiator. No clue where. I even had other people trying to help me find where it plugs. No luck.



This is a white/black stripe (Ground, I think) and a purple with green stripe wire.




Has a little corrosion Ill have to clean. 2 pins.


Any help would be greatly appreciated!

 

The first 4-pin one goes to the smog sensor for the automatic recirculation function on the air conditioner. The sensor should be mounted to the bolt hole right behind your finger. The smaller connector looks like the one for the security system sensor on the hood latch. I doubt either one would keep the compressor from kicking in, though.
