Courtesy light.

[custom10nut]

Today, I scored a courtesy light, with the two map lights, from a 95 Chevy pickup. Just eyeballing it, I think it should fit in the stock space. Has anyone else put one of these in their truck? What does it take to run power to it, so that it will only come on when I open the door, but the map lights to work hen needed? I have a complete under dash courtesy light set up, complete with the door switches. The thing I wonder is how to power the dome light separate from the map lights? I haven't mocked it up on the bench yet, so I'm just throwing questions out there for the gurus.
