Burnt wire

There is no ground!
Not in the diagram. Not in the operations.
Take the A/C out of the picture to begin with. Fix the run circuit first. Make sure nothing is grounded. J2 Ignition run - It is NOT fused. It is only 16 gage wires at best so will burn before the fuseable link.

Read through the link I provided.
1972 duster engine harness ECU electronic ignition The circuit codes are actually pretty easy once you understand the format. There's a late 60s MTSC on how to read and use the diagrams if you need.

I understand that. What I was referring to is if you look at the middle schematic you can see where the J2 splits at whatever the Diamond w 3? is. That run becomes G5 which goes to the dash and 9 pin connector THEN appears to go to a ground. Again, I could be wrong as there probably aren't too many peeps on here that know less about electrical issues than me. That said, I cranked the car over yesterday and it does have spark so I'm feeling good about that. Can't try to run it as I have a lot of stuff disassembled, carb, hoses, etc. I do know that there is only one wire that should be coming out of connection so I'm pretty confident the extra wire was for that aftermarket AC and I've removed that. Also, the dash at least as far as lighting and switches all do there job.
