I am trying to fit my HSE sound controller to my new boat - mercuirser black scorpion.
The on/off signal wire from the controller needs to connect to an anolog RPM signal - the grey wire.
BUT - the wiring loom is all sealed with a plug into the back of the mercruiser smart tow system.
Sure I could cut into the loom, find the grey wire and link but I was hoping for a more gentle solution?
looking back at the motor I am struggling to follow the loom at all.
any thoughts?
