Ok, my car didn't have AC from the factory, so I am working at installing it. I used the following parts from newer cars:

1. Heater box with AC stuff (controls, Evaporator) from my 89 Shelby Daytona parts car
2. AC cutout from my 89 Daytona.
3. H-valve/hoses/compressor from a 93-94 Spirit.
4. Evaporator from my bro's 92 parts Shadow (it was in perfect shape).
5. AC belt from one of those cars.

I installed everything and plugged everything in except the hoses/dryer.

I know the system needs to be cleaned out, but I don't want to spend money on it unless I'm sure it should work (aka it should work but may not due to me doing something wrong).

Obviously I can't connect the top plug on the compressor as my car does not have it. Will that keep the AC compressor from working?

I had my dad press the AC button in the car while I watched the AC clutch but it didn't move. In my bro's 94 Acclaim I saw it move when he pressed the button so I'm wondering if it's just because I dont have the hoses installed and the system pressurized.

All help is appreciated and please do ask questions if you think I missed something or whatever.
