    Question 96 gsxr1100 mc-4 auto shifter

    Try to wire up the mc-4 to auto shifter the bike again. I had it working last year and toke the bike apart and rebuild it. Now I cant figure out what im doing wrong. What wire puts out 12 volt when the shift light is turn on.
    red w/green shift light
    orange w/yellow shift light
    yellow kill wire

    I had a switch on the handle bars to turn on and off the auto shift. when auto shifter was off I could push the electric air shifter button and manual shift and kill the bike. The handle bar switch is three wires
    +12 red wire
    green pass thru 12 volts
    black ground.

    air shifter 2 wires
    black grounded

    please help...
