I have a 1980 Johnson 35 hp outboard that will not turn off with the ignition switch. One "m" wire is going to ground and he other wire (black/yellow) is not connected to anything in the engine compartment. I believe that wire should be going into the 3-wire connector for the ignition coils but I am a little concerned about splicing that into the black/yellow wire on the other side of the connector that goes into the power pack. I guess I'm looking for some reassurance as I do not want to short or ground out anything that should not be grounded. Thanks
