I have a 1985 pickup, 22re that came originally with no A/C. A while back I bought what was told a complete A/C system from another member out of his wrecked 85. I have all the under the hood components installed and now Im working in the cab. I have my dash apart and can not figure out what needs to plug into my A/C amplifier along with the 2 other plugs that are attached to the cooling unit itself(1 looks like it is some sort of temp sensor and the other is attached to a hard line on the opposite side of the evap inside the box.) I did find some where for the ac switch to plug into though. Also the wire that comes off my compressor needs to go to the amplifier if I have read the schematics correctly. Does anyone have any knowledge on this and pictures would be awesome. I could take pics as well if that would help. Sorry so long and thanks for any help.
