The speedometer in my 1998 M1079 usually does nothing, sometimes bounces up and down, and even more rarely appears to work. I have highway gears and EcoHubs and was going to replace the speedometer with a GPS speedometer instead of running down the errors and resetting the dip switches. And then I discovered that the speedometer is connected to the WTEC III, CTIS, and possibly the chain gun. Will disconnecting the speedometer trash any of the other systems?
