The monitor display is not where you would look. There is the monitor system control box which in my boat was located next to the main circuit breaker panel in the engine room. This is a picture of it with the connector attached; those violet colored wires are the ignition wires-Can you tell me where to locate that connector? I think there are only 4-5 wires coming out of the monitor box on dash and wires disappear into a bundle below helm area
