Do you have a test light?

Red wire for switched 12v. Hmm, could look up something in the radio circuit, blower motor, start poking some connectors and checking for 12v with the key on.

Headlights? Tap into the dash light wiring, or something that comes on when the headlights are switched..

Use a test light, its your friend.
