AC wires

[bark]

Hello was just wondering which AC wires I need in the factory harness

Computer
#14 red/blk circuit 380, refrigerant pressure sensor signal, I assume it will turn on fans, or idle motor up when ac engages


#43 dk green/white circuit 459, compressor clutch relay control, I assume this powers the relay to run the compressor

#80 blk ciruit 2751, low reference ac, no idea what this does??


fuse block
dark green circuit 59, ac compressor supply voltage, should have + when #43 powers it up

Now where do I hook my trucks ac switch into the harness to tell ac to work
