Yes, the connector is numbered. They are very small bumps, but they are numbers.
(carefull, you might get a headache reading them
)
The (2) black with red dashes are the 2 start button wires, the #11 wire goes to the (white/red dashes) headlight cut-out relay, the #12 goes to the (green/red dashes) ground circuit. This leads me to believe it may be the #11 wire mismatched with one of the headlight wires (to be determined).
