The turbo, itself, adds very little to the control system for the engine. Most everything that you see in the photo has nothing to do with the turbo. There is the ALDA and the overboost protection valve and the line from the banjo bolt at the rear of the manifold, but, that's about it.

All those linkages are related to the operation of the IP, the cruise control, and the vacuum switches on the top of the valve cover.
