Sail Panel Dome Light Wire Routing ('65 Barracuda)?

Looks like you have the buckets, lenses, lens retainers and wiring. Route your wiring with the bulb sockets down thrkk on ugh in rear inner structure out through the opening which should have the mounting holes for the buckets. Install the bulb holders to the buckets then the bulbs then this to the inner panel. Lenses and retaining rings next. You nay need to install the headliner prior to installing the buckets. Hope this helps a bit.
