Product Overviews

Step 1
Starting on the driver side, locate the three mounting locations underneath the vehicle.

Step 2
Starting at the front driver-side mounting location, locate three threaded studs on the inside of the body panel and place a 3/8″ nylon flat washer over each stud. This will help prevent galvanic corrosion. Attach the mounting bracket to the vehicle using three M8 flat washers and nylock nuts. Snug the hardware, but do not fully tighten.

Step 3
Repeat step 2 for the middle and rear brackets. Repeat this entire process on the passenger side of the vehicle

Step 4
Remove the fuse from the wiring harness before installing. Once the fuse is removed, take that section of the wiring harness and attach it to the battery. Note: If the battery is on the passenger side of the vehicle, attach the provided wire extension harness to the main wiring harness. Use the provided heat shrink on each connection to prevent corrosion.

Route the opposite end of the harness through the firewall into the cab of the vehicle. Use a cable tie to secure the wiring harness in place once it is in the desired location.

Step 5
Remove the front and rear door trim panels on both sides of the vehicle.
Remove any other vehicle components that could interfere with the wiring harness

Step 6
Once the trim panels are removed, take the second section of wiring harness and route it under the carpet, through the vehicle, from the passenger-side rear to the desired location. Refer to the diagrams below

 Wiring Locations

Driver Door sensor, rear Purple / Orange
Door sensor, front Yellow / Orange
LED light Brown / Dark brown
Actuator Black / Red
Passenger Door sensor, rear White / Blue
Door sensor, front Grey / Green
LED light Pink / Brown
Actuator Black / Red

Step 7
On the driver side, take the power wire and sensor wire (orange / yellow) and route it to the front of the vehicle underneath the carpet. On the passenger side, take the sensor wire (grey / green) and route it to the front of the vehicle underneath the carpet.

Step 8
Lift the carpet near the rear seat bracket, locate, mark and drill a 1″ hole through the floor of the vehicle. Repeat for passenger side.

Ensure there are no obstructions in the drilling location. Once the hole is drilled, take the driver-side rear actuator (red / black) and the LED light (brown / tan) and route it down through the floor. Secure in place with the provided rubber grommet. Repeat for passenger side actuator (red / black) and LED light (pink / tan) wires.
Note: If there is a plastic body plug near this location remove the plug, insert the wires through this hole, cut a slot in the plug and reinstall.

Step 9
Plug the door sensor into the wiring harness and route it up the door frame, under the carpet.
Note: If installing a door delete switch, refer to part #3020000-INS at this time. Once the harness and sensor are routed to the desired locations, wipe the sensor and door with the provided alcohol wipe. Place the double-sided tape on the sensor and attach the sensor to the vehicle.
Note: On extended cab vehicles, the magnet and door sensors will need to be mounted on the hinged side of the door. Depending on the vehicle the sensor extension harnesses may need to be used. Check for any interference by closing the door before permanently mounting magnets and sensors. Repeat this process for the other three doors.

Use of the door delete switch (part #3020000) requires manual operation of the boards. Failure to retract the boards when operating the vehicle could result in damage to the boards or vehicle.

Step 10
Temporarily position the supplied magnets on the doors in the recommended positions shown. Repeat this for the other three doors.
Note: On vehicles with aluminum body panels, non-marking tape may be used to temporarily secure the magnets. With the magnets in position complete the install of the ActionTrac™ running boards, power the system on, and test the boards by opening each door independently to ensure proper step function. Once all magnet locations are confirmed and the system is operating correctly, mark the magnet positions and permanently install using the round double sided adhesive.
Note: If there are any issues with the step function refer to the ‘Troubleshooting’ section on the last page of this installation manual.

Step 11
Locate a spot to mount the power switch bracket. The bracket can be attached using either the 3/4″ double sided tape squares, screws (not provided), or by using a factory screw if one exists in a suitable location.

If using screws confirm there are no wires behind the panel.
Connect the two red wires to the silver terminals and the black wire to the bronze terminal

Step 12
Locate a suitable location to connect the ground wire for the LED on the switch behind the dash panel. Once all wiring is installed, plug in the circuit board and place it underneath the carpet in a suitable location. Ensure the control module will not interfere with seat movement after install.
Note: To complete the installation, refer to the manual included with your side bars / running boards.


Condition Possible Cause Possible Solutions Additional Information
Boards do not open when the door is opened Power switch is off Confirm that the main power switch is in the on position and has power.
Poor battery connection Confirm the positive and negative connection on the battery are secure.
Fuse is blown or removed Confirm that the fuse is plugged in and not blown.
Control module not connected Confirm that the control module is plugged in.
Board not connected Confirm that the board connections are plugged in and secure.
Door sensors not connected Confirm that the door sensors are plugged in.
Bad motor Replace the  board. To check the motor function, apply 12 volts directly to the motor leads. If the board does not open, swap the leads and try again. If the board opens, the motor is good and swapping the leads back will cycle the board closed.
Faulty control module Replace the control module. In rare cases, the programming of the control module may be faulty. Replace if the control module is receiving power

but the boards are not functioning properly.

Boards open with the front/rear door, but not the other Door sensor disconnected Confirm that the door sensor is plugged in.
Bad door sensor Replace the sensor. To check for a bad sensor, disconnect the sensor and check for continuity with a multi-meter. The sensor is normally a closed switch and should have continuity without the magnet present and should not have continuity when the magnet is placed near the sensor.
Board is open and will not close Magnet misalignment Adjust the magnet position.
Disconnect both sensors and the board should close. Connect only one door sensor and test.

If the board closes, the alignment for that door is good. Connect the second sensor and repeat.

Bad door sensor Replace the sensor. To check for a bad sensor, disconnect the sensor and check for continuity with a multi-meter. The sensor is normally a closed switch and should have continuity without the magnet present and should not have continuity when the magnet is placed near the sensor.
Boards squeak when opening/closing Metal on metal contact Apply graphite lubricant to all pivot points. If excessive squeaking still occurs, check for worn out bushings or obvious areas of metal on metal contact.
LED light does not turn on when the step is open LED not connected Confirm that the LED connection is plugged in and secure.
Faulty LED Inspect the LED and wiring harness for damage. To test LED functionality, apply 12 volts directly to the LED. If the LED will not turn on when directly connected, it will need to be replaced.
Boards function opposite to how they should (door open board closed, door closed board open) Incorrect sensors Replace the sensors. To check for an incorrect sensor, disconnect the sensor and check for continuity with a multi-meter. The sensor is normally a closed switch and should have continuity without the magnet present and should not have continuity when the magnet is placed near the sensor.
Motor harness polarity reversed Replace the  board. If sensors are confirmed to be correct (normally closed) and board still operates in reverse, the motor electrical harness may be reversed.
After quick succession of cycling the boards
multiple times, the boards no longer open.
A programed safety limit has been reached. Using the main switch, power off the boards for 5-10 seconds and turn back on.

The boards should cycle when turned back on.

The LED will flash 8 times when this issue occurs.
Boards do not open when both front and rear doors are opened simultaneously Software limitation Close the doors and open them individually. A software limitation will prevent the boards from opening if both the front and rear door are opened simultaneously. Closing the doors and opening them one at a time will reset the board.
