I have a 1974 150 inline six mercury outboard and I need to "hot wire" it to get it started due to bad wiring in the boat. I need to know more about the wires coming out of the switchbox. From top to bottom, the first one goes to the coil, and the third one is positive, what are the other two? I think they run to the front of the boat where the key is, do they just need to be crossed for the motor to run?
If anybody knows where I could find a complete wiring diagram I would love it, my shop manual got destroyed.
