More parts identification questions.

What are these devices?  Cruise?  My steering wheel doesn't have controls and I really don't know that I'll need cruise and if I could fix it back if I did want to make it work again.  All are on the driver's side.  

The silver box is the Dura spark, but one plug is unattached.  Distributor has been replaced previous to me owning.  Appears to be a one wire Chinese electronic.   What is the plug that is plugged in?

Trying to decide whether to leave all this or try to remove some of it.

Blue box and the canister above it look like aftermarket cruise. These often came with either a replacement turn signal stalk or a little panel that screws to the dash (possibly others).

On the duraspark, the unplugged is C321 and the plugged one is C323.
If the dist is a 1 wire now the other end of C323 is likely unplugged near the dist or tucked near the drivers side valve cover. Could also be cut off... This would be C322.
This would also impact your tach if present.
