Yep, got the bracket and a hardware kit from AMK. I'm going to try to reuse the wire that connects the dome light, but unplug it from the current source to an always-hot one. I think the wiring assembly manual indicates that it connects to the interior lamps circuit BEFORE the door switch, instead of after it as the dome light does. So it may be as simple as unplugging in from one side of the switch and plugging it in the other. Of course I'm probably dreaming to think it's that easy, but all it needs is unswitched 12v for the map lights so it shouldn't be too hard to get it one way or another.
I'm interested to see how much light I'll have with the dome gone. That's all I had before, but I'll be putting in a center console, door and under-dash courtesy lamps so I'll have more bulbs anyway.
