I think by that you mean you connected the A1A segment to the A1C segment.
If so, good. You'll still want a fusible link there.
While trouble shooting, maybe the best thing will be to wire in a circuit breaker.
That way if there is a short, you won't end up with melted wires or worse.
To clarify.
A1 is the wire designation. A1A is the segment from the battery to the relay junction. I think the book calls the fusible link A1B. That's the next segment and connects with A1A at the starter relay stud. The next segment is A1C. They may have also called the segment from the bulkhead to the ammeter A1C. It varies a little depending on who drew the diagram and how much coffee they had that morning. But that's the concept.
The connectors themselves designations as 67Dart273 already described. As you know when there are multiple cavities withing the connector, they often get numbered. So wire A1C connects in cavity 16 of CE2.
Which gets us to something practical.
On your car it looks like a wider terminal is used in cavity 16. The typical Packard 56/58 type terminals are 1/4" across. If you have to replace that one, it may need to be a wider one. Point is, try to save that one if its not damaged, it may be easier to splice into the wire than track down the correct terminals.
