Model V1:
There are 4 connectors.
On the 9-pin connector, the correspondence is as follows:
light blue: right turn signal
orange: left indicator
dark blue: full beam/high beam
white and brown: crossing/night light
yellow and black: rev counter
green: negative/ground
black: positive after contact
red: permanent positive
blue and white: fuel gauge.
On the 6-pin connector, the correspondence is as follows:
green and red: neutral
pink: 1
blue/red: 2
green/black: 3
yellow/red: 4
yellow/white: 5
On the 1 terminal connector, the correspondence is as follows:
green/white: 6
On the 3 terminal connector, the correspondence is as follows:
Model V2:
9 lug connector:

orange: left indicator
black: positive after contact
blue and white: fuel gauge.
purple and black: rev counter
brown: crossing/night light
red: permanent positive
green: negative/ground
dark blue: full beam/high beam
3 lug connector:
White: + speed sensor
Green: - speed sensor
Black and White: speed sensor signal
1 lug connector:
Green and Red: 6
The tachometer (black and yellow wire) is to be installed at the negative output of the coil.
Example CB650 from 1979:
If it does not work this way (as on the BMW K100 for example), it must be installed as follows:
The probe must be installed on a support (the stirrup for example) and the magnet(s) installed on the disc. It is preferable to install the magnets as close as possible to the sensor (+/- 2 mm).
To reach the settings menu, you must lock the button for 3 to 5 seconds then switch on the ignition.
Try longer if unsuccessful.
If the problem persists, check the assembly and the connections between the permanent + and the + after ignition.
There are 4 menus. The speed display tells you what level you are in.
Menu videos:
In the first level of adjustment.
the mileage shows “CCC---”.
XXX means the default wheel circumference.
How to define the circumference? Calculate the perimeter of the wheel.
Calculation of the perimeter of a circle:
P = 2x x Radius (in mm)
Radius = Centerline of the wheel at the end of the tire.
Note: If during the test the meter has an error of 5 to 10%, you must add 5% to this result (P*1.05)
Once calculated, you can fill in the data.
The thousands number will flash at this time, short press to change the current number.
After a few seconds, the device automatically switches to the hundreds setting, then the tens setting.
Its range is 50~2600mm.
Hold the button for 3 seconds to save, then enter setting area 2.
In the second level of adjustment.
It is indicated: "y2".
2 means the number of engine cylinders is 2.
3 corresponds to 3 cylinders
4 is 4 cylinders...
Press the key to set the number of cylinders.
Hold the button for 3 seconds to save.
It is indicated on the right the value 1 or 5.
1: indicates using a 2-wire sensor.
5: Indicates the use of a 3-wire sensor.
Hold the button for 3 seconds to save, then enter the allowable mileage setting area.
To be chosen according to the resistance model of your motorcycle.
If you don't have a fuel gauge sensor, grounding the fuel gauge wire (blue and white) will cause the fuel gauge to stop flashing.
For others, you need to ground it through a 30-500 ohm resistor.
Anything more or less common has no effect. 500 ohms displays 1 bar (out of 8) or almost empty. 30 ohm 8 bar display (full screen). (about 330 ohms is half full, etc.) So if grounding the fuel wire doesn't work for you, try grounding it through a resistor between 30 and 500 ohms.
Fuel gauge sensor (example: Royal Enfield):
The basic position is "F03.4"
F = the frequency, which is used to change the speed
Once the meter setting is finished, long press the button to save and exit the menu.
