Door panel courtesy lights

[GTOger]

The courtesy lights on my 1990 ZR-1 are looking tired. The black paint is cracking/flaking on the inside, so it looks old and nasty with the light coming through the cracked places. Structurally, it's perfect. This is just a cosmetic thing. So I got some black model paint and some itty-bitty brushes thinking I'd touch it up. I managed to pop one out of the door panel, and now can't figure out what to do with it. The manual is pretty good at keeping this a secret. So I need some help / advice, if you'd be so kind. The smoked plastic lens snaps out with a little gentle force from a screwdriver. No problem. But it seems there is another piece that fits inside the smoked lens, and THAT is the part that is painted black. 2 wires go into the black painted piece, and from what I can tell, it's friction-mounted or maybe snapped into the smoked lens. The wires are not on a plug. Or at least, they don't seem to be. It looks like they are molded into the black painted piece. Any ideas on how this assembly actually fits together, and more importantly in my case, how can it be pulled apart without destruction? TIA for any assistance!
