WARNING: When installing the Shift Light disconnect the battery cables. When disconnecting,
always remove the negative cable first and install it last.
IMPORTANT: Do NOT connect to the coil (-) terminal. The supplied GMR pickup must be used
when installing the Digital Shift Light unless the rpm signal is coming from the tach
output of an MSD Ignition or aftermarket ECU. Damage to the DSL will occur if con-
nected to a high voltage trigger source.
PROGRAMMING
By pressing the two buttons simultaneous-
ly, you get the Shift Light into the different
programming modes.
RPM Points: To adjust rpm points, press
the two buttons until the rpm shows. No-
tice that all but one of the numbers flash.
The position of the steady digit matches
the gear change (the first, second, third or
fourth digit equals each gear). Adjust the
rpm then push the two buttons again to
move to the next gear.
Cylinder Count: The display will read CY
and allows you to select between one to 12-
cylinder engines using the Up/Down buttons.
PROGRAMMING
CY - Cylinder Count
12, 10, 8, 6, 6 odd, 4, 2, 2 odd, 1

Figure 1 Digital Shift Light Wiring and Programming.
Intensity: Control the intensity of the LED and read out. Hold the buttons until LuL displays. Use the
buttons to select from 9 (brightest) to 0 to turn off the shift light.
Self: Self mode will walk through all of the settings programmed into the light. It will first show the
rpm shift points for the four shifts, the cylinder count and light intensity. Start the test mode by push-
ing either button once Self is displayed. To reset the Self mode, push either button when SELF is
displayed, or turn the power Off.
Each time the DSL is powered on, the LED will display the program values that are set.
INSTALLATION
The Shift Light installs easily with the GMR Pickup or through the tach output terminal of an MSD Ig-
nition Control or aftermarket ECU. It will accept a trigger signal rated from 0-24 volt amplitude. Never
connect the Green Wire directly to the coil negative terminal.
If an ignition control or aftermarket ECU are not being used, the GMR pickup must be connected.
