68 Barracuda Instrument lights not working

I could be wrong here but are the taillights working? I always thought if your taillight fuse blows you lose the dash lights as well
Tan wire from light switch runs to fuse, then to orange wire to power the dash indicator and radio light.

Headlight switch gets power from main splice from alternator.

Headlights, brake lights, parking lights Dash lights and map / courtesy all get powered from that always on feed.
