While your looking into the wiring and the dash is out, you might want to look into how the seatbelt interlock is connected/bypassed. It only allowed the starter to operate when the seat belt was latched. I thought it was a '74 only thing, but that little box with the red button by your HEI module looks like part of the system. Been so long, but I remember at module under the dash that I removed and connected two wires.

I was curious now and I noticed when I was under the dash yesterday that some of the ignition harness from the key was cut and spliced. Looking at the wires from the plug, do in fact, go to that block/module that I posted earlier. I am suspecting that that is how its being initially bypassed.
