Nearly all the cruise controlls use a cable activated by an electrc servo controll motor (old ones used to use vacume) Speed is controlled by electronic speedo signal (in the days of mechanical speedo magnets were fitted to drive shaft & pickup coil). So once the speed was set it would try & keep that speed. Much easier for an auto, in manuals there should be aswitch on the clutch pedal to disengage cruse control to stop engine from over reving. Also brake switch to disengage cruise. Fitted a lot of after market cruise controls to new petrol & diesel vehicles. Wth new vehicles Eg ford drive by wire throttle body, hasto be matched to engine computer as it now controls throttle opening, that bit takes a bit of geting used to. Daryl

A lot of good advice has been given , Dave06 sumed it up very well .

The bottom line is that no two rigs are the same ,so its not a case of one size fits all .

Every one should know their vehicle , its ability & performance , the feel & sound .

If you have this ability, you realy dont need any tacho,s speedo,s etc

to be able to drive your rig according to the conditions .

Remember the old saying ;; drive by the seat of your pants ,

If it feels good , ok .

if it dont , then you are doing something wrong .
