What is this thing?

I have a new to me 96 cavalier. It has problems like jerky cruz control & some times head lights/day time running lights. Under the hood I have found a box screwed to the upper cross member above the rad/starter. Off of it are 2 wires that go to the passenger side control box, one grey and the other blue. One is marked tac signal the other speed signal. This box has a vacuum line run to it and has a cable run to the throttle. The blue wire has run against the belt and been cut through. Also the used to be a hood pin for a command start (there is a command start sticker on the air cleaner) but it is missing and there is no trace of the wire. There are also ther wires for a remote start run to it. I just want to rip this out as I have not remote for it.

If you are going to Remove the Cruise Control (picture) be sure to cap Vacuum Hose & disconnect  the Throttle ......You may have a Vacuum leak or loose Cruise Throttle connection now if the Cruise is " JerkY "MO
