I have a 1989 johnson 200gt I will get the serial number for it tomorrow when there is light.
I had the motor worked on last year and last week after taking out to the lake I was just checking the motor over and ran into a problem. On the left side of the motor if standing behind the motor and looking towards the front of the boat there is a wire that I see is not plugged in that goes to a black box. I included pics. Does anybody know what that wire is for and do I plug it back in? The boat ran fine so I do not know what to do. The only thing I have done to the motor lately is removed the VRO and premixing the oil.
TIA
