On most of the 700 and 900 cars that I have had , I have fitted the liumated switchs off the later cars, also you can change the switches for the rear doors in the drivers door so all for light up (just be careful when fitting the switch as the mount is frigale). Note that the mirror switch working changed around 1991/1992 , they look the same and the plugs are the same but they are not the same and are not compatible and were fitted with the new type mirror motor. Also on 940's the 1997/98 cars had a auto down on the driver door ,that you can fit by changing the door loom to the later type along with the realy out of the door. Regards RogerB
