i have a older merc 115hp inline 6 2 stroke outboard, the tac harness coming out of the front of the controlbox has 3 wires, white, black and brown. The tac has only 2 poles marked pos and neg. is this the wrong tac? The previous owner had the white and brown to the pos and black to neg and melted the white on the harness. I pretty sure the white is pos black grnd and brown signal. There is a small bolt in the center of the tac that isn’t marked.
