1987 g20 No rear interior lights. Checked fuses in fuse box. Looked for aux fuses behind driver seat. There was fuel tank selector instead. I need to know where the feed for power to the rear lights comes from.

You want to add rear lights because there are none, or they don't work?
If the former, just run back from the front dome light.....If you are worried about adding to an existing circuit use an led bulb .
My 95 g van was an uplevel model....chrome bumpers quad headlights, power windows and locks...etc. If I remember right there was an over ride switch to turn the rear lights on and off at the back of the van.

From the Fuse Panel Box.
You need to get a schematic for that year. I can tell you on the newer years like mine the positive wire is blue with a white stripe. Orange may also be used. The two colours depend on the intended functioning of the lights.

It is a conversion with about a foot added to the roof. The lights are controlled by three switches that are mounted in the roof over the console along with a cb radio that is also dead. It's as if there is an override switch or fuse that I can't find. There are dome lights on each side and in the rear that aren't working. Two lights over the console come on when the door is opened

First, I'd pull that CB out and with a volt meter or a test light, determine if you have power there at all. Also, look to see which direction wires go. This will help in tracing where power comes from.
Is this a custom van, or a camper? Any idea who did the conversion?

Thanks for your interest and help. I believe this to be a Gladiator, no camping eqpt just captain chairs and a couch. There isn't enough spare wire to pill out the cb. Can't tell the direction or color of the wires. Wires to the side lamps are white and black. Wire to the black are dark blue and grey. If becomes necessary to trace wires. I can do that. A schematic for this unit would really be nice. I was hoping someone would say there's switch hidden in the spare tire or such.

Well.. it's custom so... it might even have a secondary fusebox. In the modern vans GM provides a high amperage four wire connector for an upfitter to build from. This gives the upfitter negative, battery, run... and possibly one other. It could be the same on yours. The upfitter might have taken that lead and added a fusebox somewhere. Who knows. Good luck.

Sooner or later, the bulbs in the rear lights burn out. It would seem that it's easier to take a new light bulb, suitable for the size of the base and voltage, and install it instead of the burned out one. If you install low-power bulbs in your brake lights and direction indicators, other drivers will simply not see your signals in inclement weather. And powerful lamps in dimensions will greatly interfere with drivers driving behind and annoy them. For example, I used a fairly powerful and I didn't even need special tools for replacement, except for a screwdriver to unscrew the two screws from the side of the trunk seal.
