There are only THREE main circuit busses in the stock A bodiy boxes

"HOT" buss. This is everything that is hot with IGN switch off, such as brake lights This buss comes in on a big no12? no10? wire which comes from the "in harness splice" in the ammeter circuit under the dash

"Switched ACCESSORY" buss. This group is fed by a big wire which comes from the IGN switch, and is hot with IGN in either "ACC" or "RUN" This feeds the fuses like wipers, radio, heater, etc

"Instrument light fuse". This little guy is off to itself, electrically

The headlight circuit is fed from the "in harness splice" and there's a breaker in/ on the switch, ONLY for the headlights.

Tail/ Park and instrument lights get power TO the switch from the tail fuse. AFTER this power goes through the cluster dimmer control, THEN it goes to the fuse box through the "instrument" fuse, and then off to the cluster lamps, or any other lamp that is on the instrument dimmer, such as the radio dial.
