I just bought a 2007 Caravelle with a 4.3 Mercruiser. Upon inspection I find three wires not connected to anything. They lay just behind the carb and come out of the main wire harnes. Two are black and one is orange. Except for stalling at idle, the boat runs out fine and all instruments work. Any idea what these are for?
I have a 2007 mariah with a 4.3 that I just replaced the engine. There were a few open wires. mine is fuel injected, but those wires were not connected to anything. They just laid on the intake. I have a few junctions that were either capped off or just laying unconnected as well.
