unknown connector???
 

Just bought '89 ranger with 2.9l has a/c. Fixing several things and found plug under hood, passenger side of engine. One wire is orange the other is green and I don't know

Attachment 148133

what it plugs into or is for?? I have attached a pic. Thanks

Re: unknown connector???
 

It looks like the connector that plugs into the pressure switch on the filter/drier for the A/C.

I have a plug on passenger slide near the fire wall. It is a code wire. Should be a single wire plug to. Look up codes for your truck. Mine kid a 91 4+4 ranger.

Thanks for replies..turns out last owner removed the sensor that it plugged into on the a/c dryer!! Thanks for help!!
