Trying to figure out where this goes on the aftermarket radio or harness since it’s directly attached in factory radio. Also, factory radio has 2 wires, new harness has 1 and wiring diagram I’ve found on forum shows one. Thanks for the help

That has to be an early 1st gen, you should specify year since that looks nothing like the later year 1st gens.

I think that connector was for the clock constant power.
