What goes where

[ayjay]

You know it says in the book to photograph the engine layout of your donor to avoid problems later on----well Does anyone know where the bottom of the plastic expansion tank connects on a 1.8cvh? I think the top one goes to the thermostat housing.
Also is the screw in hosetail under the pierburg carb on the inlet manifold the the servo connector? If so can I just find something with the same thread to blank it off?

Thanks
