Looks like some kind of temperature controller for those electric fans. It's a shoddy job of shoe-horning salvaged parts into a C3, but may work just fine. If it does, I would certainly suggest that you clean up the horrid wiring job done previously. Also, the power for the fans/controller should be fed directly from the battery or from the primary alternator stud, so that the current load isn't going to damage other [smaller] power wires.

1. do the wires from that part actually connect to the fans?
2. Where does the hose on the bottom of the first picture connect to?

If that doesn't run to the fans it looks like a electrically powered air pump. Used for emissions

It looks to me like a Bosch air pump that Volkswagens came with (Jetta/Golf).....they may be using it for vacuum.

Yup they ran electric air injection smog pumps for a number of years on GM cars, and that looks like one of them.

Never heard of such a thing. I have an electric air pump on my 1995 Oldsmobile Silhouette for the air suspension system, but it is larger than that, and under the back floor. Lou.

I too thought it was the A.I.R. pump.

Not to be confused with an air suspension compressor - this is the system that puts fresh air into the exhaust to catalyze the burning of unburnt fuel.
