Help!!!

The wires you show on the duramax arre the kill wire from the ignition coil than when connected to ground either thru the switch turned to off or if the low oil sensor sees low oil will ground out the wire and stop the motor. You would need to have lighting coils on the engine and if the engine has them it would come out from under the cooling shroud in the front of the motor and usually has a plug just like your bikes plug in the photo. The black wire coming out with the white plastic plug is the lighting coils AC output.
