96 cavalier remote start?

Hi, I have a new to me 96 cavalier. It has problems like jerky cruz & 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. Oh yeah 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. I just want to rip this out as I don't know what it is and I have not remote for it. Grog

I uploaded a picture but I don' know where it went? It was named "remote" Grog
