68 Barracuda Instrument lights not working

Re. Mattax's excellent diagram, do the parking lights and headlights get power from the black wire? And if so, they are not fused?
And why not supply power to them via the pink, fused line? I can understand the headlights drawing too much power relative to the dash and dome lights, and needing a separate feed, but where's their fuse and parking light fuses? I'm in same dilemma, no dash or dome lights.
