I need to know what the wires on the three screws on the side of the motor go to. Or I should say two of them, I know that one goes to the choke solenoid by process of elimination. But the other two go underneath the fly wheel. I bought a new internal wiring harness and don't wanna screw this up with my genius use of a multimeter. (which I'm doing good just to turn that thing on and off) Any help would be greatly appreciated. The motor did not have one when I bought It so I have to figure this out. I have the external wiring harness that was made by mercury, but the new internal that I bought was aftermarket so I'm afraid the colors will not match up correctly.

Thanks,

The diagram is a big help thanks.But in the diagram where it calls for the "salmon" colored wire, the closest thing to salmon on my new harness is orange.

On your new harness does the orange wire go to Pin F on the plug? You say that the colours do not match up. What colours do you have and what pins are they attached to on the plug?
