I pulled the air conditioning lines out of the front clip from a 89 plymouth sundance and hooked it all up finally got all the bugs worked out and put the systen into my 94 shadow i had to change the bracket that the compressor mounts to and that was about it. The question is on my car the 94 shadow i have a high pressure sensor pig tail that hooked up to the compressor that i took out for the swap, do i need to hook up like a paper clip or a diode to the clip to have the car's electrical system think that everything is normal or should i have to do something else?
