You may be confused with the front Parking Lights that extinguish when the headlights are on. The OEM Squarebird headlight switch 'A' terminal supplies power at all times. That is why the door lights, also fed from the 'A' terminal, do not depend on a key or headlights to be on. According to the 1960 wiring diagram, backup lights shine when the shifter is in reverse.
The 'A' terminal simply has a fuse between it and the Batt terminal. It's the upper fuse, clearly shown in this picture:
The yellow power wire is on the upper left and the green brake light wire is on the upper right ('A' terminal).
This is picture #12 but the entire switch can be viewed HERE.
No need Joe, it already happens that way on Squarebirds from the factory.
Squarebirds are wired so that backup lights shine whenever the shifter is in 'R' regardless of the time of day. No, clock power comes off the Batt terminal with an non-fused yellow wire that feeds the cigar lighter as well.
