On my Johnson remote control, I have a small rubber connector protruding. It has 3 wires. Black, Blue and Grey.
I know that the Black is ground. Can I assume that the others are ignition + and the other one is a sensing wire for the Tacho. I take it that the Blue wire is live and the Grey wire is the sense wire for the tacho.
Please correct me if I'm wrong so that i do not do any damage. Thanks for any help.
