Alternator C1 connection wires?

That's a fairly common modification. As with most innovations that directly benefit car owners over benefits to the manufacturers, Chrysler has led the way since the 1950s. Most notably, they developed the "AC generator" for 1960 models, and copyrighted the term, "alternator". They were also the first to have an electronic voltage regulator in 1970. It was a real popular unit for modifications. In fact, I'm using one on my New Holland skid steer to get its generator working again.

Here's the charging system diagram. The next two drawings are for the Engine Computer connector C1. Next two are for connector C2 etc.

Besides the power wire, the other two wires go to the PCM. Here is the alternator wiring diagram so you can see how to rewire the system back to stock. Check out the images (below). Let us know if you need anything else.

These are the same drawings, but for your purposes, I added two callouts to the diagram. These are the two wires you need at the Engine Computer, (PCM). The last two are the same wire lists for the two connectors, but I highlighted the two wires you need.

Let me know if I failed to cover something, otherwise let me know if you run into trouble.
