Thread: UDX dash and external shift light

  1. #1

    Default UDX dash and external shift light

    Can you connect a UDX dash to provide a signal to a MSD 8963 shift light? The 8963 is completely programmable 1-12 cylinders. How would you set up the dash and connect everything? Connect the orange wire to the signal to the shiftlight?

    Hmm....interesting. I don't have a UDX but in reading the PDF, it seems the UDX outputs a on/off signal only. Like you would use for a regular light 12 volt light bulb/and or a relay, to act as an external shift light.

    The MSD 8963 is more advanced and looks like it is looking for a square wave signal and reads the rpm directly and you would then program the shift light. So either hook the MSD 8963 up independently of the UDX, or not use it and just use a regular two wire shift light or light bulb like perhaps a Autometer 5330?

    Your reading the same thing I am. Maybe someone from racepak can chime in and confirm.

    The UDX dash outputs a ground-trigger signal which can operate an LED-style shift light. It cannot power an incandescent bulb style shift light.

    Hope this helps.
