vacuum diagram m103 260e

[optimusprime]

Just purchased this new thermovalve to replace the one on my car .Would anyone have a good vacuum lay out diagram for the m103 engine. For some reason i think the old one is pluged in wrong ,ie one connection on to the pipe of the valve is off set ,other one sits upright. If i had one i can then check the small bore pipes [vacuum ] to see the right place to connect up to. Checked out google for hours ,and images and no help.
