d) the location of the signal source
(alternator, coil or other ignition
signal source).
2. Connect the wiring to the appropriate
tachometer terminals as shown in Diagram
C.
Configuring the Tachometer:
Before your VDO Tachometer will func-
tion properly with your engine, you will
need to configure it as shown in Diagram
D.
The table at the top of Diagram D shows
how to set the DIP switches for use with
an ignition coil; the table at the bottom
shows how to set the DIP switches when
using the tachometer with an alternator.

Tachometer wiring with Alternator AC Tap (left); and with Ignition Coil (right)
another type of ignition system, determine
the number of pulses per revolution the
ignition signal provides, and set the DIP
switches as shown in the bottom table.
Adjusting the Tachometer Pointer:
Use of the VDO Tachometer with an al-
ternator or other type of ignition that pro-
vides a signal in pulses per revolution may
requre calibration of the pointer.
This can be done as show in Diagram E.
Please note that this calibration is designed
to adjust the reading between 30% and
100% of the RPM range.
At this point, the installation and wiring
of your new VDO Tachometer is complete.
Turn on the ignition and the lights in the
car and check to see that the instrument
and light work properly. If they don’t, re-
check your wiring, referring to the wiring
description in Diagram C.
