The tachometer (light blue 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 (<8 mm).
To reach the settings menu, you must lock the button for 3 to 5 seconds then switch on the ignition.

Note: it's not the same counter but it's the same principle.
Short press to set value and long press to change settings.
"----" means the default wheel circumference.
How to define your 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.
XX means the default. The setting range is 1~12. This is the number of magnets installed on the wheel.
There are 2 magnetic steels in the package, so please change the number to 2.
It might be better to place the two magnetic steels in a different angle of the tire.
Two magnets are normally more accurate than one (faster speed refresh). In some cases the difference is minimal.
Note: it is best to try with 1 or 2 magnets to find out which configuration suits you best.
Hold the button for 3 seconds to save, then enter the cylinder number setting area.
2 means the number of engine cylinders is 2.
Single cylinders and double cylinders do not need to be tuned (default=2).
3 corresponds to 3 cylinders
4 corresponds to 4 cylinders
Press the key to set the number of cylinders.
Note: Attention once configured, it is impossible to reconfigure it without starting all over again.
Hold the button for 3 seconds to save, then enter the fuel meter wire number setting area.
