MSD Tach Driver
PN 8913
Parts Included:
1 - Tach Driver, PN 8913
1 - Butt Connector
3 - Mounting Screws
2 - Bullet Connectors
Caution: The Tach Driver cannot be used with a Capacitive Discharge Ignition (such as an
MSD Ignition Control). The voltage on the coil positive must be below 18 Volts.
INSTallaTIoN
Note: It is recommended to have a wiring schematic of your vehicle's ignition system to clearly identify
the Coil Positive (12 Volt ) supply wiring.
The MSD Tach Driver wires inline on the positive 12 volt supply wire. It senses current on the coil
positive wire and converts it to a 12 volt signal output. To install the Tach Driver, the coil positive wire
must be identified for your application. Once the wire has been located it is recommended to check
for 12 volts using a volt meter. Connect the meter and turn the ignition On. In some cases, the engine
must be cranked over in order to see 12 volts.
The Tach Driver is designed to be mounted under the hood. The circuits are potted in polyurethane
for water resistance and vibration protection. Position the Driver away from excessive heat sources
and mark the locations of the three mounting holes. Use a 5/32” bit to drill the holes and secure the
unit with the supplied screws.
Route the wires away from direct heat sources, moving components and sharp edges. Use the
supplied bullet terminals on the 12 volt coil wire. (These terminals are supplied so the wiring can be
returned to stock if ever desired.) The butt splice crimp connector is used for the Gray tach output
lead and the tach trigger wire.
Red
