radio intallation

The wire that runs the dimmer....does that go to a constant power or to the accessorie power? I cant remember which one I hooked it up to but now my damn parking lights come on when I crank the car and I can dim them with the little swivel under the light switch. The radio lights nor interior lights dim now. I used a plug harness so nothing factory was cut.
AND, does anyone have an extra coin tray? lmao....guess what happened to the old one!
