I think there was some connection of A/C with the old distributor's coil -ve terminal. And as I have now not connected anything with new distributors -ve terminal, maybe that's why the A/C is not working. I need you to elaborate it. And how to connect the A/C wire to new HEI Magneto distributor?

This should not effect the operation of the compressor according to the wire diagram.

What is the make of the magneto?

I have the wiring diagram of A/C of my car, here the A/C amplifier pin # 5 is connected with Ignition Coil's -ve terminal, I am here uploading the snapshot. Maybe that's why now the A/C is not working? As the new HEI Magneto Distributor is now connected with A/C amplifier pin #5. Kindly elaborate.

Should I connect the previous coil's -ve terminal to the new HEI Magneto distributor black wire, coz it has only two wires on it, one is of +12V DC, and other is a black wire (maybe also used for tachometer but my car does not have RPM gauge), so maybe this black wire on new magneto HEI distributor is for A/C amplifier pin # 5?

This black wire you are pointing is going to igniter, and in my car the igniter was mounted on the coil.
