I am going with a 4bt motor in my 89 k5 blazer and an nv4500 tranny. i want to have cruise control but not sure how to go about it. I have a stock 1997 dodge ram cummins cruise control thing with the cable and all just dont know how to make it work.... it deffinatley runs off vaccume so that is not a problem and the cable hooks into the throttle linkage so that shouldnt be a problem. I just need to know how to control it. It has a plug on it that has the electical part. that is where im stumped. I would be happy just to have the on off function work(i dont need the slow or accel feature just on or off.) Anyone here have any first hand knolwedge on how to make on of these work? thank you all.
