Installation guide
Mechanical speedometer with integrated speed sensor in the speedometer cable
Remove the signal from the speed sensor, extend and connect to 
socket A pin 1.
Minimum requirement for the signal:
0 Hz - 4 kHz / square-wave signal (no inductive sensor)
Low - level < 1.5 V, high - level 5 V - 16 V
Mechanical speedometer without speed sensor in the speedometer cable
A speed sensor which generates a digital, speed-dependent signal must 
be installed in the speedometer cable.
The VDO adapter 2152.30300000 or a vehicle-specific adapter which 
satisfies the minimum requirements can be used. The VDO speed sen-
sor is suitable for direct installation on the gearbox (no further installa-
tion parts required) or in the speedometer cable (in conjunction with 
additional universal installation parts).
If you do not know the exact installation position / location of
the speed signal, please consult the vehicle manufacturer.
If the sealed speedometer cable is released, a correct display
cannot be guaranteed. Incorrect installation leads to improper
functioning of the navigation system or of the speedometer.
