Default 69 wiring help

Hey guys first post I'm trying to help my dad put his C3 back together after some issues with the heater blower motor and I can't figure out where this wire goes to. It will start but the center gauges are dead and I've checked them they're all hooked up. Any ideas I've referenced the Haynes book and can't figure it out. Thanks for the help!
Mystery wire.

Attaches to the heater resistor (which is on the plenum).

Search the forum for wiring diagrams from member @robertea . They are fabulous.
