Ultimate swap confirmation

Hi I've got a new under dash wiring harness, I don't believe it has provided for the factory reverse indicator light of which I've misplaced. Do you recall where/ how your indicator light got power? My new reverse indicator light has a black wire with no terminal.
Thanks

As told above, it's quite simple.
Just connect the black wire to the "Z" terminal in the bulkhead connector
The bulb is grounded by the mounting on the metallic dash frame.
