1967 fastback interior questions

Both sets of wires run down from sockets down to rear of car. Make sure you do all mods/updates(led bulbs, new plastic bulb holders and new harness).
Well worth the effort.
Thank you! I am finding by probing with a wire that (so far) i cannot seem to get into the cavity just above the sail panel, right above and behind the quarter window.

I'll take a pic in the morning and report back.

Have a great weekend!
