Fuses nearly always near the drivers left foot. Question from there is inside or outside.
Those lights were usually daisy chained together. Across the front, and then again across the rear. 2 connections at each light, power in, and power to the next light in the chain. They generally grounded using the alum skin, but if material is fiberglass, the lights will probably have a common ground wire.
Start at the driver's side top and work your way across to the passenger side (wires generally run up through A pillar). Pull the light and see if one of the wires has power. If so, repair the light as required and move to the next light in the string. Easier than it sounds once you figure out how it's wired.
