the optional standard dash map light & switch panel light bulb



That looks a little confusing ebodyseast. Could you explain that a little better?

The map light is on the bottom edge of dash frame by passengers left foot.
The title lamp lights up the switch panel.
The ignition lamp is the one in the steering column.

Just from memory, I was thinking all 3 came with the optional A01 light package, which was available with OR without rallye dash.

I didn't look at the diagram for this, but I'm thinking the map light has steady power with switched ground (typically yellow wires), the title lamp has steady ground with switched power (typically orange wires), and the ignition lamp is hooked up with the time delay somehow.

Seat belt lamp would be time delay too.

P.S. As a side note, the map light location moves from the dash frame to some plastic trim on AC cars, but I don't think this affects the wiring harness in any way.

Also the ignition lamp changed between 70 & 71. I'm not sure if that affected the wiring connector or not.
