POWER
Connect the red wire from the 4-wire main harness to accessory power from the ignition switch. Connect the
WHITE/RED wire from the 4-wire main harness to constant battery power. The WHITE/RED wire keeps the clock
time and the RED wire lights up the gauge.
Never connect this to a battery charger alone. It needs to have a 12 volt battery connected to it. Battery
chargers have an unregulated voltage output that will cause the system to not operate properly.
GROUND
The BLACK wire from the 4-wire harness is the main ground for display system. A poor ground connection
can cause improper or erratic operation.
SPEEDOMETER
Failure to calibrate the speedometer may cause your odometer mileage to increase very rapidly.
The speed input connector plugs into the speed sensor to tell how fast you are traveling. On cable driven
applications, the SEN-6011 (sold separately) connects to the speedometer cable and provides the electric signal.
This
arse thread fitting that accepts mid-8
speedometer cable will need to be replaced with a cable having the correct fitting. Custom cables can be made, or
stock cables can be modified for many of the Metric applications.
With transmissions having the built-in electric sensor, the supplied three-wire harness adapter connects the
transmission speed sensor to the speedometer. This system will also accept most after-market inductive, Hall-effect,
or ground switch sensors.
For 3 wire Hall-effect sensors, refer to the installation instructions for the sensor to determine wire color code.
Most 3 wire sensors use the following color code: RED power, BLACK ground, WHITE speed signal. Connect
the sensor signal wire to the GREEN wire from the 3-wire harness, connect the sensor power wire to the red wire from
the 3-wire harness, and connect the sensor ground wire to the black wire from the 3-wire harness.
For speed sensor integrated into a vehicle wiring harness(most
Metric Cruisers
w/factory VSS utilize a 3-
wire Hall-effect sensor), consult a service manual to determine the color code and location of the speedometer signal.
If the factory harness su5V to the sensor, please utilize the factory connection in place of the red
power wire.
For 2004+ Harley and 2003 V-Rod
applications
green wire on the speed
sensor to make certain the ECM will still receive its proper VSS signal from the sensor.
2006+ Sportsters
utilize a black/blue wire for the VSS signal in place of the white wire on most big-twin models.
The speedometer is fully adjustable and calibration is described on page 5. VSS wires should be isolated
from the ignition system. Coils, plug wires, or tachometer signal wires
routed near or with the VSS wire can cause:
erratic speedometer operation, speed reading at a standstill, incorrect or difficult calibration.
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.
For tach signals integrated into a vehicle wiring harness, consult a service manual to determine the color code
and location of the tachometer signal.
For 2004+ Harley and 2003 V-Rod
The tachometer signal will come from the negative side of the ignition coil. Blue/Orange for the front cylinder,
Yellow/Blue for the rear cylinder, connect the tachometer input to
only one
of these two wires, set the tachometer for
a 1 cyl signal, see Tachometer Set-up for instructions.
INDICATORS
The right turn, left turn, and high beam indicators are activated by 12 volts at their respective hook-up wires. The right
turn signal wire is GREEN, the left turn signal wire is ORANGE, and the high beam wire is PURPLE.
The neutral, low oil, and check engine indicators are activated by ground at their respective hook-up wires.
The check engine wire is PINK, the low oil wire is BROWN, and the neutral wire is WHITE/GREEN.
These can be connected to the signal wires for the original indicator lights.
The display system wire colors may not match the wire colors in your electrical wire harness; consult a service manual
to determine the color code and location of any wires you cannot locate.
The WHITE output speed signal normally attaches to the GREEN/WHITE wire of a stock Harley turn cancelation
module.
Aftermarket TCM modules, that do not use speed to self-cancel turn signals, will not need this wire.
LOW VOLTAGE WARNING
When the voltage drops below the warning limit with the engine running, the battery indicator will illuminate.
(default warning limit is 11.0V)
