Harness Diagram:
The wiring harness includes the following connectors:
- A: CIRCUIT BOARD CONNECTOR
- B: MOTOR CONNECTOR
- C: LIGHT CONNECTOR (Optional)
- D: REAR DOOR SENSOR CONNECTOR (Green wire)
- E: FRONT DOOR SENSOR CONNECTOR (Blue wire)
- F: ROCKER SWITCH CONNECTORS
- G: ROCKER SWITCH
- H: BATTERY TERMINALS
- I: FUSE HOLDER
Harness Routing:
Passenger Side: Trace the harness from the rear passenger door along the frame rail to the front. Secure the harness with zip ties to factory harness points.
Driver Side: Similar routing, ensuring access to the front of the Jeep.
For 2-Door Models: You will have extra harness length. Secure excess with zip ties.
Harness Route: Located outside the Jeep, attached to the top of the frame rail, and underneath the vehicle attached to the crossmember.
IMPORTANT NOTES ON POWER CONNECTION:
- JK MODELS: You can connect the red (+) and black (-) wires directly to the battery terminals, or connect the ground wire to an existing body bolt.
- JL MODELS: Must connect the ground wire to an existing body bolt. Connecting both wires to the battery terminals will result in a loss of 6 inches of harness length.
Step 1: Installing the Passenger Side of the Harness
- Ensure the fuse is removed from the wiring harness.
- Trace the passenger side of the harness with the fuse case, red wire (+), and black wire (-) from the rear passenger door along the frame rail.
- Fasten the first junction of wires to the existing factory harness with a zip tie behind the middle body bolt. Leave the remainder of the harness at the passenger door free.
FOR EASE OF ACCESS:
It is recommended to remove inner fenders if installed. This provides easier access to the harness from the wheel well to the lower battery area through the engine bay.
Step 2: Connecting to the Battery Terminals
- ENSURE THE FUSE IS PULLED FROM THE WIRING HARNESS.
- Continue to run the red wire (+) and black wire (-) with the fuse case through the wheel well area, using the factory access hole below the front passenger wheel well.
- Attach the red wire (+) to the positive terminal and the black wire (-) to the negative terminal of the battery.
- Alternative Ground Connection: You have the option to run the black ground wire to an existing body bolt on the Jeep. Ensure good metal-to-metal contact, free of paint interference.
Step 3: Floor Plug Installation
- Pop the rocker panels on the front and rear of the passenger side to access the floor plug and wiring.
- Place the black grommet into the floor plug; it will bend to shape.
Step 4: Routing Harness and Sensors
- Thread the green door sensor (D) and blue door sensor (E) connectors up through the floor plug on the passenger side. The circuit board (A), Motor (B), and light (C) connectors will remain visible on the passenger side.
- Pull the remainder of the harness from the passenger side to the driver side over the frame rail. Run it along the cross member and secure the RSE Harness with zip ties.
Step 5: Installing the Driver Side of the Harness
- Pop the panels on the driver side and remove the carpet to expose the floor plug.
- Thread the green door sensor (D), blue door sensor (E), and rocker switch (F) connectors through the floor plug and into the cab.
- Leave the rear green door sensor (D) in the back. Run the front blue door sensor (E) and the Rocker Switch (F) along the existing harness towards the front of the Jeep.
- The driver's side circuit board (A) and motor (B) connectors remain outside the Jeep. This side should resemble the passenger side, but without a light connector (C).
Step 6 - Part 1: Installing Rear Door Sensors
- Starting on the rear doors, remove the trim panel on the B pillar.
- Run the rear door sensor (D) along the existing factory harness.
- Using alcohol wipes, clean the area above the rear door hinge.
- Attach the double-sided adhesive to the back of the sensor and press firmly.
- Expose the adhesive on the foam wire protector next to the sensor and wrap the foam around the frame metal.
- Connect the door sensor to the green wire (D) connector.
IMPORTANT: After installing sensors and magnets, test one door at a time. Plug in the fuse and ensure the magnet is correctly positioned. The step should deploy when the door opens and retract when it closes. If the step does not deploy, adjust the magnet's position.
IMPORTANT: Rear door sensors are located on the INNER portion of the door on the B Pillar.
Step 6 - Part 2: Installing Front Door Sensors
- Remove the trim panel on the front door.
- Run the front door sensor (E) along the existing factory harness.
- Clean the area directly below the door latch striker with alcohol wipes.
- Attach the double-sided adhesive to the back of the sensor and press firmly below the door striker.
- Expose the adhesive on the foam wire protector next to the sensor and wrap the foam around the frame metal.
- Connect the door sensor to the blue wire (E) connector.
- Tuck all carpeting back in and reinstall the plastic rocker trim.
IMPORTANT: After installing sensors and magnets, test one door at a time. Plug in the fuse and ensure the magnet is correctly positioned. The step should deploy when the door opens and retract when it closes. If the step does not deploy, adjust the magnet's position.
Step 7: Door Magnet Installation
- Clean the metal inside the door with an alcohol pad.
- Peel off the backing from the adhesive pad, attach the magnet, and press firmly into place.
- REAR DOORS: Magnet location is on the inner side of the door, opposite the sensor on the B Pillar. Remove the clear plastic from the adhesive pad, remove the brown paper backing, and press the sticky sides together. Test fit your location by keeping the blue plastic cover over the adhesive tab. Mark your magnet location and place it.
- FRONT DOORS: Magnet location is on the outer part of the door, opposite the sensor below the door striker. Position approximately 1/4 inch down from the bottom screw below the door latch.
IMPORTANT: Perform a test fit to ensure the magnet is properly aligned with the door sensors. See Step 6 Part 1 & 2.
Step 8: Rocker Switch Installation
- Follow the driver side door strap to the bracket.
- Install the master switch cutoff bracket onto the JK door strap bracket by loosening the screws and sliding it into place.
- Pull the wires through the bracket.
- Plug the red and black wires into the two-prong switch (polarity does not matter).
- Push the button back into the bracket until it snaps into place.
Step 9: Mechanical Installation of the Step Sliders
- Remove two front pinch seam bolts using a 10 mm socket and wrench. Keep the hardware for re-installation.
Step 10: Body Bolt Preparation
- Starting on the passenger side, locate the three body bolts on the underside of the vehicle.
- Loosen these body bolts approximately 1/4 inch to allow free movement of the washer up and down. A breaker bar may be required.
- TIP FROM A MECHANIC: As you loosen the bolts, if you hear or feel them bind, reverse direction 1/8 to 1/4 turn to clear the threads and prevent damage.
IMPORTANT: Rock-Slide Engineering is not responsible for any body bolt damage. Consult your Jeep dealership or a qualified mechanic for assistance.
Step 10 Continued: Install each bracket between the bolt head and the washer, leaving them loose for now.
Bracket Identification Mark:
JK Bracket Identification Mark is a small notch on the bracket.
IMPORTANT: In some cases, the washer may not allow enough gap. You may need to use a small file to remove the two threads closest to the washer.
Bracket Types: 1. Rear Bracket (long style, 5 3/8 in.), 2. Middle Bracket (short style, 4 5/8 in.), 3. Front Bracket (drop style).
Step 11: Bump Strap Installation
- Clean the angled section of the Jeep's body near the pinch seam with an alcohol pad.
- IMPORTANT: Before placing the bump strap, perform an alignment check. A good location is 1 3/4 inches from the bottom of the door seal to the top of the bump strap.
- Slowly remove the adhesive backing as you align the bump strap to the Jeep's body, holding it in place. Press firmly where the tape is removed.
IMPORTANT: Once adhered, the tape is designed not to come off. It protects the Jeep's paint and fills the gap between the Jeep and the Step Slider.
Step 12 - Part 1: Step Slider Installation
- Starting on the passenger side, pull the circuit board (A) and motor connector (B) through the last cutout between the last bolt and the step slider bracket mounting hole before placing the Step Slider on the Jeep.
- Insert the bolts on the step slider into the pinch seam holes. The Step Slider will stay in place.
- Secure the Step Slider to the seam using the 1/4" and 5/16" nyloc nut and washer sets.
- Plug the circuit board (A) and motor connector (B) into their ports. The additional wire on the harness is for the optional light kit connector (C); tuck it inside the step slider for later installation.
- Tighten the pinch seam nuts: 1/4" nuts to 8 ft. lbs., 5/16" nuts to 18 ft. lbs.
IMPORTANT: Ensure wires are not pinched between brackets, the Step Slider, or the Jeep's body.
Step 12 - Part 2: Final Tightening
- Reinstall the two 10 mm panel pinch bolts. Torque to 8 ft. lbs.
- Tighten the body bolts to 80 ft. lbs.
- Repeat this process on the driver side.
Step 13: Calibration Cycle
- With both step sliders installed, reinstall the fuse to allow the circuit board to calibrate.
- The steps will deploy and retract rapidly; this is normal.
IMPORTANT: Ensure nothing obstructs the steps during deployment and retraction. If obstructed, remove the fuse and rerun the calibration cycle.
Step 14: Finishing Touches
Use the provided plugs to cover the holes in the Step Slider.

FREQUENTLY ASKED QUESTIONS:
Q: My steps are not coming down when I open the door.
A: Double-check all connections. Ensure the fuse is properly seated, the on/off switch is receiving power, the circuit board is plugged in, and the door sensors are connected. If the rocker switch is getting power but the light stays on in both positions, switch the red wires on the back of the switch. This will not drain your battery unless left on for an extended period without use.
Q: The steps do not deploy unless manually powered with 12V.
A: Test the motor by unplugging it from the harness and applying 12V power directly. If the motor deploys and retracts, plug it back into the harness. Motors are tested before shipping but can rarely fail. If you hear a clicking sound but no movement, the motor may be internally damaged. Contact Warranty@rockslideengineering.com for a replacement circuit board if the motor functions correctly.
Q: The system shut off after opening the door multiple times.
A: The systems have built-in protection against rapid cycling. Remove and re-install the 20-amp fuse to reset the system.
Q: I want to remove my doors and have the steps still work.
A: Rock-Slide Engineering sells a door delete kit (Part # SL-DD-100) for this purpose. You will need two kits for all four doors.
Q: The steps deployed and won't retract.
A: This is likely due to misaligned magnets. To diagnose: close the front doors and unplug the rear sensors. If the steps retract, the rear doors need alignment. If they stay down, the front doors need alignment. Open the door, shift the magnet, and close the door. Repeat until the step retracts. Mark the magnet's position. Reconnect the rear sensor, close the rear door, and test. If the step still doesn't retract, the rear door magnet needs alignment.
Q: How to test sensors and align magnets?
A: Unplug both sensors on the non-working side. Plug one back in. With the door closed, place a magnet very close (but not touching) to the sensor. The step should retract. When the magnet is moved away, the step should deploy. If the steps deploy immediately after installation, the magnets likely need alignment. Test and align each sensor and magnet individually. Mark the magnet's position for future reference.
Q: I went off-roading, left the system on, and ripped my step off. What now?
A: Rock-Slide Engineering can replace parts at cost. You will need to remove the step to replace internal components. Contact them for assistance with parts or repair services. You will cover shipping and parts costs; they will cover return shipping.
