I have an 89 ramcharger with a 318 with factory no ac. I want ac and so far I have acquired many of the parts; ac compressor and lines, heater box with the ac options, control box, and ac vents and ductwork. Has anyone else done this? I’m wondering if I can just mount the ac compressor in the same place it’s mounted on every other 318 where the idler pulley is. What else do I need (besides the condenser)? Will it just hook up to the under dash harness I have in there now? Does anyone have pictures of a completed ac system under dash and under hood?
