okay it been a while since i been in a 240, i had a ka-t and never had to worry about hooking up a/c. i just got my hands on a 1990, 240sx with a sr20 redtop in it. first on the list to do is a/c the car has no a/c components what so ever. i just bought a complete a/c system from a guy here in town from his s13. looked like it was from a sohc.

1). I know i need a sr bracket to get most of the ka compressor bolts to fit? (correct me if i'm wrong)
i've also herd a 95 pathfinder bracket will align the pulleys perfectly?

2). I'm going to wing it and put the stock ka system back in but i checked for wiring plugs but can find them, I.E. wire to compressor, and the one on the small canister. i just need to know what to plugs these into? or at least what color the wires are so i can splice it, or location to reline these wires.

3). I also know that splicing a couple of wires in the pins will get the a/c button to work in the car and run like stock?

no a/c is not a options its hot in Florida!

any parts i need i will gladly buy from you if you have them!

I can't remember what color the ac wire is but id turn the ac on and check the voltage to the wire you think is it. I know the ac relay is blue w/green stripe if that helps.
