Switchover Valve 190E
 

Hey all:
I purchased the updated switchover valve 201-800-05-78 that replaced the two switchover valves in the climate control system of the 190E. Does anyone have the Mercedes service bulletin on how to install the updated version? It looks like I have to use a T to connect two vacuum lines to one connector of the new switchover valve...is this the case and can I use any type of vacuum T? Also, which of the two electrical connectors from the old valves goes where? Thanks in advance.

Ok I figured out that all I have to do with the vacuum lines is simply T them. However, the plugs from the two old switchover valves (one has 4 connectors, one has 5) are not marked, so how do I know which receptacle to plug them into on the updated switchover valve? Thanks in advance.

just plug them in! If the flaps don't work correct plug them in the other way.
