Class A - Carbureted. Does anyone know (or have a picture) of where the ECM connector is located or what it looks like. Also my check engine light does not work. I thought locating the ECM and tracing it back to the CEL might be the easiest way to find out where the wire is cut. And although cryptic, it might be nice to see the codes.

On the carb unit I don't think there is one. I have never seen one on mine.

From fading memory (a risky proposition) if the motorhome has an oxygen sensor in the exhaust, it must have an ECM to drive the carb's mixture control solenoid. It should also have electronic sensors for other things, like manifold pressure, etc. I don't think these were used on units without catalytic converters.
