If your CS did not have the roof console, the wiring will have to be modified for the Map lights to work.
Cars that have a Dome light have a single wire going to it (Black with a Blue stripe) for power when one of the doors is open to illuminate the Dome light.
When installing a roof console the Dome light is no longer used or required. The trick is to locate the Black/Blue wire in the passenger door switch area. Unplug it (bullet type connector) and find a DIFFERENT connector that has a Green/Yellow stripe wire going into it, and plug in the Black/Blue wire you had previously unplugged. Now you have a 'Hot' wire in the Dome light area. Connect it to the Map Light bullet connector in the roof console and the Map lights will work using their individual switches.
Too bad you guys live so far away- wish I could be there, and show you.
