Diff Lock Switch

[Andrew Pennell <apennel@vermontel.com>]

I am currently retrofitting my current quattro differential switch to the later style found in the 90 series cars. The switch I am after is in the 90 Coupe, for example. If anyone has a Bently's for a 90 series quattro's, could you please give the part numbers for the components to the differential lock switch. I think there is the switch itself, and a solenoid to turn the vacuum on and off. If anyone could give me a response I would greatly appreciate it. - Andrew
