General Installation Notes:

Please read instructions completely before beginning installation. If

you have any questions please call.

Before starting installation, use wheel chocks to block the wheels.

Do not attempt to install this product while the engine is running.

Disconnect the negative battery cable before beginning installation.

Make sure the engine, transmission, and frame are properly grounded.

We recommend applying anti-seize lubricant to all aluminum threads

before final assembly.

Refer to Fig. 1, 2 and 3 for the component names.

MOUNTING OPTIONS: The Lokar Cable Operated Indicator Kit is equipped to

mount the sensor either on the transmission using the attached bracket, or

in a remote location within 5 feet of the transmission selector shaft using the

provided universal sensor bracket.

To mount the sensor remotely inside the vehicle, a Lokar Remote Mounting Cable

Kit (part # CINR-1796) will be required. This extends the cable 7 feet, for a total

of 12 feet.

The decoder box should always be mounted inside the

vehicle and out of the elements.

When installing the sensor and sensor bracket directly

on the transmission, they can be installed on either

side (all except TH400 transmissions). Installation on

the right hand side is recommended, because it

provides more room to get the cable straight in line

with the selector shaft trans arm. (NOTE: On a 700-R4,

it may be necessary to remove the factory hex head 1/4"

pipe plug and install a socket head style pipe plug. Fig. 4)

On a TH400, the sensor and sensor bracket must be

mounted on the right hand side of the transmission or

in a remote location.

Step 1: Assemble the upper and lower parts of the

adjustable cable mounting bracket, installing

two #8-32 x 5/16" button head screws and

lock washers using a 5/32" Allen wrench, but

do not tighten the screws fully yet. Fig. 5

Step 2: Both standard (5/16"-18 x 1-1/4") and metric (M8 x 30mm) transmission pan bolts are provided for mounting the adjustable cable mounting bracket, and for mounting the sensor bracket directly on the transmission. Make sure you match up the threads from your original pan bolts to determine which new bolts you will need to use. The standard and metric threads may appear very similar at first glance.
PAGE 3
Step 6: Remove the existing regular nut from your selector shaft. This kit includes one standard 3/8"-16 trans arm nut and one metric 10mm trans arm nut (has nicks on hex). Install the trans arm nut that has the correct threads onto the selector shaft. Step 7: Place the 3/8" internal star washer onto the standoff bolt that matches the trans arm nut you installed on the transmission. Then install the indicator trans arm onto the standoff bolt, and install this assembly into the trans arm nut.

Mounting The Decoder Box The decoder box must be mounted in a dry place. When mounting this unit, keep it within the reach of the wires on the LED display and the sensor. The decoder box can be mounted with two screws or doublesided tape. Be sure it is still accessible to connect the wiring and for programming. Wiring The Sensor and The Decoder Box The sensor has a 10 foot long gray cable attached to it. This cable contains 3 wires which connect to the decoder box.
PAGE 5
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.

The following steps are specific to the type of transmission you have. For TH350, TH400, or TH200: Step 1: Shift the transmission to Drive. Step 2: Press and hold the set switch. The OVERDRIVE light should remain on steady. (If the light will not quit flashing, then the sensor is not moving.) Step 3: Release the set switch. The OVERDRIVE light will go out, and the DRIVE light should begin flashing. Step 4: Press and hold the set switch again. The DRIVE light should remain on steady.
