Some tachometers or factory fuel injection systems may not interface directly with an MSD Ignition
Control. The PN 8910 is designed to correct this problem by producing a signal similar to the factory
setup for these applications. The PN 8910 will convert the trigger signal into a signal the factory
tachometer or fuel injection recognizes.
Note:
The PN 8910 is designed for non-current limiting (originally equipped with a ballast resistor)
such as breaker points or optical triggered distributors.
INSTALLATION
1. Mount the Tach Adapter in a location away from direct engine heat making sure the wires reach
the MSD unit and the coil.
2. Splice the White wire from the PN 8910 into the MSD's White (trigger) wire.
3. Splice the Red wire from the PN 8910 into the MSD's Red (switched 12 volts) wire.
