just added the factory cruise control to my 86 J10 and have it working perfectly now with lots of help from some great posts on this site. I have one final thing I still wonder about, shouldn't there be a light on the dash cluster that lights up when the cruise is engaged? If the truck didn't originally have cruise did the cluster not have this indicator or is it still there and just somehow needs to be hooked up? Not a big deal but I am kind of picky about having things done how they were originally and I would like to add it if possible.
Anyway, my question is should there be a light on the dash the comes on when the cruise is engaged?
