4 Speed Reverse Light Plug In

[Nuke463]

I have 71 Superbee 4 speed car. Reverse light is mounted on lower dash. I can't find where the reverse light plugs into. Where do I plug this at Any suggestions?
Thanks!

Bulkhead connector - possibly terminal 'Z' .....the terminal is either empty, or showing signs of a Black wire with white tracer cut off.
