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.

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.

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.
