I'm not sure about greys on early units, but I'm balding from all this head scratching. Good catch.
docnjoj, you don't actually have brakes do you? Nothing to actually tell the controller to enter regen mode.
Whatever these wires are they they don't have the right kind of termination to continue the wiring around the bike. Unlike the cruise control that does.
I can't escape the voltage idea. It says 30/40v lvc and a 36v pack goes over 40v when full. I do note however that the meter requires a short time to stabilise, needing to see a bit of use before it will display. Perhaps the story lies in how they sag.
Here is a similar manual http://king-meter.de/images/download/bedienungsanleitung/KM-JLCD%201.pdf
The same site has a similar unit where each battery segment seems to want setting http://king-meter.de/images/download/bedienungsanleitung/KM-KM5S%203.pdf

KT_LCD Apparatus Advanced Configuration Options Function
KT_LCD apparatus advanced setup function is only usable to professional technician.Advanced option parameter:
P1_motor character parameter,P2_motor velocity signal pulse parameter,P3_Power-aided mode parameter, P4 is the
startup mode , P5 is the power monitoring mode.
1.Enter advanced setup interface
A.,The advanced setup is not accessible unless f irstly enter the general setup menu(such as velocity-limitation
parameter, wheel diameter parameter, metric or English unit selection).
B.Press the button SW to stop the three common parameters from flashing.
C.Press the button UP and DOWN synchronously for 2 seconds to enter the advanced option setup interface.
2.Set advanced option parameter P1
P1 is motor character parameter, and equals to reduction ratio multiplied by rotor alnico number.,If decimal fraction
appears, round off first.,After enter the advanced setup interface, it is found that the parameter P1 flashes, you could use
the button UP and DOWN to adjust the P1.
3.Set advanced option parameter P2
P2 is motor velocity signal pulse parameter.Afterset the P1,short-press the button SW to set the parameter P2.If the
wheel rotates one time, the pulse equals one, then P2 is set as one ,if the wheel rotates one time, thepulse equals six, then
P2 is set as six. If the motor is not equipped with velocity signal outputting function, you could set the PS as 0.Attention:if
P2 is set as zero ,the following defect maybe appear,when the motor stop rotating or the internal rotor rotates slower than
the external rotor, the velocity indicated on the apparatus may be incorrect.
4.Set advanced option parameter P3
The P3 default setting is zero, power-aided mode i s five speedy grade. If the P3 is set as one, it indicates that the
power-aided mode is five-grade torque drive mode.Parameter should be determined according to the function of the
controller, the setting method is as same as described hereinbefore.
All the advanced option parameter setup finishes, long-press the button SW to save the settings and exit.
5. Set the Advanced Parameters P4
P4 is the startup mode of the switch-handle. P4 equals to 1, indicating a non-zero startup mode of the switch-handle
(that is to say the switch-handle can only be effective after the start of the pedal power). When P4 equals to 0, it means the
switch-handle is on zero startup mode, (that is to say the switch-handle can start the motor directly).
6. Set the Advanced Parameters P5
P5 is the power monitoring mode. P5 equals to 0, indicating the power monitor is under the mode of "immediate voltage".
In other word, it is the method to judge the battery power according to the immediate voltage of the battery. When P5 equals
to a specified parameter, the battery monitor is under the mode of "smart power" (the parameter is determined on the basis
of the battery characteristics, it is generally between 4-11 for the common 24V lithium,
and 5_15 for 36V lithium).
7. Parameter Saving
Press on SW key for long time to save and exit the condition of configuration
parameters at the same time after the adjustment ofthe configuration parameter.
8. Installation Method for Vehicle Speed Sensor
When the KT_LCD instrument matches the high-speed motor without signal for
speed output (with built-in clutch), it requires anexternal vehicle speed sensor. The
installation method of the external vehicle speed sensor refers to the right picture.
Note the relative position relationships of magnet and sensor. When the KT_LCD
instrument is connected to the external vehicle speed sensor, set the parameter of P2
as 1.
