[Bolting for Dollars]

This function is activated by the red wire of the rear camera connect to the positive wire of the reversing light.

Where is this wire for a 2023 Bolt EV?

The back up camera on my car has intermittent issues, I want to install this as a back up and the dash cam capability.

Firstly, welcome!

Can’t help with wiring questions, but I’d think you’d want to get the intermittent camera issue addressed first, under warranty? Especially if you’re planning to do any mods that they could potentially blame the camera problem on you.
