See p 66 of this PET. It shows the correct vacuum routing for 1978/79 w/o lambda. The thermovalve is 17A. As you can see it is between the lower chamber of the WUR and the lower port on the throttle body. Since I don't have one I rely on a slightly lowered cold control pressure, which it looks like you had on your previous WUR.
