It was an part as part of the Tone Door Popper assembly. Mostly, it was just a nice long piece of wire and a pin switch. You would install the pin switch in the back door and run the wire up to the similar switch at the passenger door. It made the lights turn on when you opened the back and also tied it into the alarm.

You probably could source the pin switch pretty much anywhere, but I'm not sure. My kit was missing the pin switch.
