Electronic Speedometer; Signal Ground - VDO Speed alert Installation Instructions Manual

In vehicles with electronic speedometers, the Speed Alert signal wire (Blue) can be directly
connected to the speed sensor signal output.
You may need to refer to your vehicles service/repair manual or contact your local Dealer to find
out the speed signal colour wire.
In the case of a mechanical speedometer, fit an electronic speed sensor to the vehicle as per the
instructions of that particular unit.
If the speed sensor supplied in the mechanical Speed Alert kit doesn't suit your application,
contact VDO Kienzle or your supplier for further information on alternative speed sensors.
