I am installing one as we speak. This is the secound one on our Boss's. It does all of the same things as your automobile will do. The servo is about 4" in diameter and fits under the left side panel facing the rear with the cable looping around going to the carburetor. You have room and all will work well unless you have L.E.D's for stop lights. The unit uses the stop light bulbs as a ground and when the brakes go on the power shuts them off.Larry said:A few weeks back there was some discussion about the Audiovox Electronic Cruise Control. Could someone please give some more details as to how it works. Does it work off of the speedometer. Does it have a control box and where do you mount it. Does it have a cable that pulls the throtle or what. Also when you hit the brake or turn off the throtle will it turn off. Also where did most of you mount the control. Anyone have pictures.
