I have upgraded my (EE80 2E engine) Point Distributor to HEI Magneto Distributor and A/C not working

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?

Do you
have the same problem?

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.
