I have an 82 f150 with factory ac. There is a 2 wire plug that connects to the top of the compressor. There is a third green that follows the same way but is just hanging there. Ive looked but dont see a place for it to go. Is this for the high pressue switch if so where should it connect. Thanks in advance

 

I have an 86 F-150 with the same problem. I made the same post several weeks ago & no one has helped. I'm trying to find someone with a similar truck WITH AC so I can snap a pic. If I find anything, I will definitely let you know.

 

Thanks. Does your ac work? I was thinking maybe a good detailed picture of someones engine may help but was unable to find one.
