MMDC on a 2003 48 Sedan Bridge with Cummins QSM11 engines quit, - same not
available. Would like to replace with analog gauges. MMDC input shows engine input as Red White twisted pair+ & - or NEMA, plus a white wire Tach?. Inputs for Ignition both switch and key are known along with fuel senders.
Engine has sensor for oil and temp but no idea where the wires go as Sea Ray did not provide diagrams for same. Possibly they go to the Sea Ray Systems Monitor?
If anyone has done this conversion, would appreciate any help/diagrams etc.
