Exclamation 190E: Does anyone have a vacuum and wiring schematic

diagram so that I can test the push button controller, the switchover valves (vacuum gates) and the various vacuum elements for an 87 190E 2.3?

I have been working on the heater core, it is in but now I am trying to sleuth with the push button unit which doesn't do anything to the system.

I have read where sometime solder joints go bad. Should I check any in particular?

I APRECIATE any help provided right now .... starting the second weekend of repairs ....................... ... .. .
