Questions on wiring Ignition/ supplying power to the fuse box


I don't know how this every worked and it seems labled wrong Originally, one large red came to the stud from the battery, and the other went through the bulkhead connector with a fuse link in series. Originally this went to the ammeter, and after passing through the ammeter the black on the other side of the meter became the main master power feed for the interior of the car. That went to a splice which fed the ignition switch, the fuse panel "hot" buss, the headlight switch (headlights only) and branched off (black) back through the bulkhead and to the alternator.

The "middle cyan" on the "square" terminal should go to the starter solenoid

One of the bottom ones gets grounded through the transmission neutral safety switch, and the remaining one gets the "start" signal from the ignition switch
