A/c with no computer.

So after researching a bit, I found this link with a wiring diagram.

My question is how do I make the compressor cycle properly and regulate line pressure or does it still do that because of the pressure cycle switch? I know this defeats the WOT clutch cut out, but aside from a loss of power keeping the a/c on at WOT will it indefinitely damage the system to not have it functioning? Also, where do I find these wires? The whole harness has been removed (unplugged) from my car, so where are these wires hiding, in the dash or in a wire loom under the hood? Am I missing anything else from the equation to make this work?
I wanna get my a/c working, 100+* here lately is great motivation.

Thanks.

Since you live in NJ which is strict with emissions, you are going to have a harder time passing emissions inspections without a working computer system.

Thanks, but this swap was done 2 years ago. It passed the sniffer with the right tune at a shop. That was my last inspection on the car. It now has historic plates since it isn't my daily driver so no more inspections for me.

Pre-computer cars just relied on the low pressure switch to allow the compressor to go on. So if there wasn't enough refrigerant in the system, it cut the compressor off. Later cars had a high pressure cut-out on the high pressure side and I don't see why that can't be retained just as a safety feature. Aside from that, once the AC is turned "ON" from the dash it's pretty much self regulating and it is critical that your refrigerant charge is within the specs for your car. Might as well keep the WOT cut-off too. IIRC the AC wiring came through the firewall in the same place the computer wiring did, on the passenger side below the glove box area.

When I removed the CCC system from my 84 SS it was totally independant on a seperate harnesss and never touched the HVAC wiring.
