I have been trying hard to find a solution to the bad lighting inside the e30, not being able to look through a cd binder. I know there is a rearview mirror with dual maplights out there..but anyone know how you wire that into a 325 (non i) model? I'm guessing its just a single + lead and the metal ground. If anyone knows if this maplight mirror can be made to work in a 325e would appreciate some advice.
