The part number for the switch you want to use is :
f8rz-14529-ab
Don't forget the D79 connector to power the LED !

I'm not sure what to say about a "matching" rear dome light . Since you've got a Mystique , you've already got the light I had to add ... . I guess you'll have to "browse" the dealer's lots for one that looks like it'll fit . Better yet , maybe wander around a junkyard pulling down dome lights & measure the holes .
