Re: Power supply to the rear accessories

You are on the right track. The body feed wire comes off the accessory circuit breaker which in a 22nd series is toward the top of the cluster above the clock and goes over the headliner along with fuel sender, tail light and turn signal wires going to the trunk. If it is not hopelessly faded the body feed is a red wire with white tracer and goes to the rear courtesy light where it stops. If you have a model with lights and a cigar lighter in the front seat back, there is a splice above the center pillar and a wire drops down the center pillar just behind the front seat and feeds those too. Power is supplied directly from the BAT terminal at starter solenoid and via a couple of splices that wire feeds the breaker, ign sw, and headlight sw so the breaker and body feed wire should be powered at all times.

The front courtesy or vanity lights also are fed by that accessory breaker so should always be hot too. The front cigar lighter is fed from the wire supplying the breaker and headlight sw via a splice or connection near the headlight sw but it does not go thru the breaker.
