We have a 1994 Coachmen Catalina/Spartan chassis with a 6.5 chevy diesel. The tachometer and speedometer have quit. We were told by one mechanic that it was the ECM.
He said there were two, one in the front and one in the back. My question is, does anyone know where they are located; or could it be another problem. Have looked but don't know
what to look for. Another problem would be to find them and get them reprogramed. Any information would be helpful!
