Backup light and neutral safety wire harness for 71 a-body w/auto trans?

(the second link reads like it's universal, but if you click on the link and read it's not. HU232N)

All the rest they show are for manual trans only. Not sure why this one isn't available (or so hard to find).

Thanks

The harness connector is just 3 wires. Left and right ends are reverse lamps, middle wire (brown) is neutral safety. I can't imagine a difference in the harness other than wire length. The switch itself,,, getting the correct one can be a headache. Good luck
