I'm working on this too. My 97 gtp sedan has courtesy lights in the front doors with a clear spot in the red and just the solid red lens without a bulb in the rear doors. I bought complete doors from a 97 gt for parts and they all just had the solid red lenses in all four doors with the plug in the front doors for a light but the lens housings are not set up to power bulbs. I'm planning on splicing the wiring together in the rear doors but I need to come up with lenses that have the provisions for bulbs or fab my own. Has anyone else done this?
