Re: Boston whaler rage 14 wiring.
im not sure.
Your red looks so small id say that the green is probably your main positive.
You could try and see if the green wire has continuity with the positive on the starter solenoid then you would know it is the positive.
It could be the positive for the trim and tilt so you could see if hooking up black and red makes the engine go but not the trim and tilt.
