Reply to "backup light switch"

Some of the '72 cars had the +12v for the backup lights connected to fuse 3, which is one of the parking light fuses. That required the parking or headlights to be on in order for the backup lights to work.

Most of the cars had the +12v for the backup lights connected to fuse 12.

If your backup lights only work when the parking or headlights are on, find fuse 3 and look for a small gauge green wire that is connected to fuse 3. Disconnect that wire and verify that the backup lights no longer work. Connect that wire to fuse 12. Any spare terminal on fuse 10, 11, or 12 will work.
