87 190D, OM602 turbo diesel

Hi 'ya folks, I'm trying to better understand the IP pump in my 190D. I stumbled across two items that I cannot name and therefore I cannot google search them.

What is this electrical connector for?

What is this gizmo for?

Thanks!

The electrical plug on top is for the rack position sensor. It's for use with the EDS computer to adjust EGR flow and idle performance.

The "gizmo" on the side of the IP is the VCV for the transmission. It's a variable vacuum "leak" to make the modulator work properly for smooth shifting.
