Programming The Gear Positions
Programming is done using the push-button set switch located below the sensor
connection terminals and watching the programming LED’s (not visible until power
is applied) located between the sensor connection terminals and the body of the
decoder box. The

PARK light is directly behind the PARK terminal, REVERSE light is

directly behind the

REVERSE terminal, etc.

NOTE: For the programming procedures below, you will be watching the LEDs on the
decoder box, NOT on the boot indicator or dash indicator.

Step 1: Place the transmission in Park and make sure the key is off. Reconnect the

negative battery cable.

Step 2: Press and hold the set switch. Fig. 14 Turn the ignition key on while

holding the set switch down. Then release the set switch.

Step 3: The lights will come on either all green or all red. All green means the

decoder box is currently set for ground (-) outputs, which is correct for a
Lokar indicator. If you are using a Lokar indicator and your lights are all
green at this point, proceed to

Step 4.

If the lights are all red, that means the decoder box is currently set for
positive (+) outputs, which some other brands of indicators use. If your
lights are all red, and you are using a Lokar indicator, press and release the
set switch. This will change the mode of the decoder box to ground (-)
outputs. The lights will then turn green, and you can then proceed to

Step 4.

If you are using an indicator from another manufacturer, determine if your
indicator requires ground (-) outputs or positive (+) outputs. Press and
release the set switch if needed to put the decoder box in the correct mode
for the other manufacturer's indicator. Follow the instructions provided with
the other manufacturer's indicator.

Step 4: Press and hold the set switch for a few seconds until all the red and green

lights turn on, to save the setting and put the decoder box in programming
mode. Then release the set switch. For a Lokar indicator, the program
lights on the Decoder Box should now be red with the

PARK light

alternating between green and red.

Step 5: Press and hold the set switch until the PARK light remains on steady.

Step 6: Release the set switch. The PARK light will go out, and the REVERSE light

should begin flashing.

Step 7: Shift the transmission to Reverse.

Step 8: Press and hold the set switch. The REVERSE light should remain on steady.

(If the

REVERSE light will not quit flashing, then the sensor is not moving.)

Step 9: Release the set switch. The REVERSE light will go out, and the NEUTRAL

light should begin flashing.

Step 10: Shift the transmission to Neutral.

Step 11: Press and hold the set switch. The NEUTRAL light should remain on

steady. (If the light will not quit flashing, then the sensor is not moving.)

Step 12: Release the set switch. The NEUTRAL light will go out, and the OVERDRIVE

light should begin flashing.
