    Hi, I'm working on a custom chopper for a friend. It has a Diamond Digital Speedo on it and no wires were hooked up to the thunderheart controller. Does anyone know where to get a wiring diagram for the speedo? Have tried searching web but to no avail. Is Diamond Digital even around anymore?
    Thanks

    Found this on another site:Did you use this set up guide?

    SPEEDOMETER
    The speed input connector plugs into the speed sensor to tell how fast you are traveling. On cable driven applications, the external sensor connects to the speedometer cable and provides the electric signal. The sensor is normally bolted directly to the bottom of the speedometer, but can also be remote mounted. The sensor has a 5/8" course thread fitting that accepts mid-80's and earlier cables directly. For newer cycles the speedometer cable will need to be replaced with one having the correct fitting.

    With transmissions having the built-in electric sensor, a three-wire harness adapter connects the transmission speed sensor to the speedometer. This system will also accept most aftermarket inductive, Hall-effect, or ground switch sensors. This speedometer is fully adjustable and calibration is discussed below.

    SPEEDOMETER CALIBRATION
    The speedometer calibration is done using the function (trip) switch. The speedometer can be calibrated two different ways. The first method is to place the unit in auto-cal mode and drive exactly one mile (one km for metric). The second method is to place the unit in adjust mode and the speed reading can be moved up or down while driving.

    The speedometer will provide a reading before it is calibrated, but it may not be accurate. If the speedometer will only show 00, then it is probably not getting a speed signal. Check all of the wiring and mechanical connections carefully. If you are using a stock electric transmission sensor, remove it and check for metal filings on the magnetic end. If you are using a cable-driven sensor, make sure the cable and sensor are turning. If you are using a gear-tooth or bold-head sensor, check the spacing to the steel target (these sensors will not read aluminum or stainless steel targets).

    METHOD 1, AUTOCAL
    Make sure the key is off so the gauge is not powered.
    Press and hold the function switch.
    Turn the key on. With the switch still held, start the bike. The display will show "DISPLAY" "..".
    Release the function switch. The display will switch between "AUTO" (auto cal), "ADJ" (adjust), "CYL", "SET", "BAR", and "VOLT". The odometer will show "SELECT".
    When "AUTO" is displayed press the function switch. This will place the unit in auto calibration mode.
    Release the function switch. The odometer will show all zeroes.
    Drive exactly one mile (or 1 km). The odometer value will be calculated and stored. The gauge will now restart in normal mode with the new speed calibration.
    METHOD 2, ADJUST SPEED
    Make sure the key is off so the gauge is not powered.
    Press and hold the function switch.
    Turn the key on. With the switch still held, start the bike. The display will show "DISPLAY" "..".
    Release the function switch. The display will switch between "AUTO" (auto cal), "ADJ" (adjust), "CYL", "SET", "BAR", and "VOLT". The odometer will show "SELECT".
    When "ADJ" is displayed press the function switch. This will place the unit in calibration adjustment mode.
    Release the function switch. The display shows the speed and odometer will show "ADJUST"
    Drive at known speed. Following another vehicle that is driving at a constant, known speed can do this.
    Press the function switch. The speed reading will begin increasing until the function switch is released. The next time the function switch is pressed, the speed reading will begin decreasing until it is relaxed.
    Once the speedometer is reading correct release the function switch. The new calibration will be saved if no adjustments are made for 7-10 seconds.


    SPEED OUTPUT FOR TURN SIGNAL CANCEL MODULES
    The display system also has a speed output signal for cycles equipped with an automatic turn signal cancel module or cruise control. The white wire from the controller harness should be connected to the module where the wire from the original analog speedometer was connected. The wire from the original speedometer is usually a white/green wire.



    TACHOMETER
    The tachometer is used by connecting the yellow wire from the main harness to the negative side of the coil or to an ignition module tach output. The tachometer is adjustable for 1-15 cylinder settings. The 1 cylinder setting is used for single-fire ignition systems without a buffered tach output.

    The following instructions are used to set the tachometer output:
    Make sure the key is off so the gauge is not powered.
    Press and hold the function switch.
    Turn the key on so the gauge is powered. The display will show "DISPLAY" "..".
    Release the function switch. The display will switch between "AUTO" (auto cal), "ADJ" (adjust), "CYL", "SET", "BAR", and "VOLT". The odometer will show "SELECT".
    When "CYL" is displayed press the function switch. This will place the unit in tach calibration mode.
    Release the function switch. This display will switch between "1 C", "2 C","15 C."
    When the desired setting is displayed press the function switch. The display will show "DONE."
    Release the function switch. The system will not start up normally with the new setting.


    TACHOMETER RED LINE/SHIFT INDICATOR
    A single bar will light up to indicate a shift point or red line. The rpm where the bar lights up is user selectable and can be turned off completely if desired. The bar is factory set to about 6000 rpm.

    The following instructions are used to set the tachometer warning bar:
    Make sure the key is off so the gauge is not powered.
    Press and hold the function switch.
    Turn the key on so the gauge is powered. The display will show "DISPLAY" "..".
    Release the function switch. The display will switch between "AUTO" (auto cal), "ADJ" (adjust), "CYL", "SET", "BAR", and "VOLT". The odometer will show "SELECT".
    When "SET" is displayed press the function switch. This will place the unit in the shift/red line set mode.
    Release the function switch. The bar display will star at 2 and begin moving up. After it reaches the top it will go out and then start back at 2.
    When the desired rpm setting is displayed press the function switch. To disable this feature, press the function switch while the bar is not displayed. The display will show "DONE" once the new setting is stored.
    Release the function switch. The system will not start up normally with the new setting.


    TACHOMETER BAR RANGE
    The tachometer bar can be set to 0-5000, 0-8000, or 0-16,000 rpm full scale range. The bar is factory set to 8000 rpm full scale.

    The following instructions are used to se the tachometer bar range:
    Make sure the key is off so the gauge is not powered.
    Press and hold the function switch.
    Turn the key on so the gauge is powered. The display will show "DISPLAY" "..".
    Release the function switch. The display will switch between "AUTO" (auto cal), "ADJ" (adjust), "CYL", "SET", "BAR", and "VOLT". The odometer will show "SELECT".
    When "BAR" is displayed press the function switch. This will place the unit in the bar range set mode.
    Release the function switch. The bar display will show 5000 scale, the 8000 scale, then the 16000 scale.
    When the desired rpm bar scale is displayed press the function switch. The display will show "DONE" once the new setting is stored.
    Release the function switch. The system will now start up normally with the new setting.

    Hope this helps, is this how you wired it?
