How to Bleed 4Matic
 

I need to bleed the 4Matic system on my 1993 300E. AllData has information on how to bleed the system for the rear differential (e.g. connect the 8 and 2 leads from the 4Matic computer to activate the rear diff valve), but I did not find any information on which leads to connect to activate the valve(s) for the transfer case. Does anyone know the right leads to connect on the 4Matic computer?. thanks...Doug
