    Shifting issues related to electrical wiring

    The main engine connector. Look at the drawing you posted If the wire is not there, then OMC didn't install it. If not installed, then this might also mean the switches are not there either

    Shifting issues related to electrical wiring

    You should have the wire and it comes from pin 4 of the connector. The alarm switches have one wire because when activated they apply a ground to the engine block. If the wire is not on pin 4 then it was removed or something strange happened
