Step 7 – 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. Use the alcohol wipes to clean directly below the door latch Striker. Making sure the surface area is clean and ready for the door sensor adhesives.
With the door sensor in hand, use the double sided adhesive and attach it to the back of the sensor. Press the sensor 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.
When you are finished, you can tuck all of the carpeting back in and reinstall the plastic rocker trim. Snapping right into place.
IMPORTANT
After installing sensors and magnets, only connect one door at a time. Plug your fuse in and make sure the magnet is in the correct location. If it is, the step will deploy when you open the door and retract when you close it. Once you know the door is working,
remove the fuse and move onto the next door. If the step does not deploy, you may need to adjust the location of your magnet.

Step 8
DOOR MAGNET INSTALLATION
Using the alcohol pad, clean the foam on the inside of the door. Peel off the backing and firmly press the magnet into place.
REAR DOORS: Magnet location is on the inner side of the door. Opposite where the sensor was placed on the B Pillar. Close your rear door after placing the sensor. Opposite the sensor, on the inner part of your door, a foam piece will indent slightly. Place your magnet in the center of the indented foam.
FRONT DOORS: Magnet location is on the outer part of the door. Opposite where the sensor was placed below the door striker. Roughly 1/4 in. down from the bottom screw below the door latch.

TIP FROM A MECHANIC As you start loosening, as soon as you hear the bolt pop or feel it bind, reverse direction 1/8 to 1/4 turn to clear the threads. This will make it easier as you progress. Even if you do not hear it pop do the reverse direction early on to prevent body bolt damage.

IMPORTANT
RSE is not responsible for any body bolt damage. Please visit your Jeep dealership
or regular mechanic for assistance.

Step 13
BUMP STRAP INSTALLATION
In preparation for the bump straps, make sure the angled section of the Jeeps body near he pinch seam is thoroughly cleaned. Wipe it down with an alcohol pad after.
1 3/4 in. from the bottom of the door seal to the top of the bump strap is a good location.
Be sure to line up the extension piece bump strap straight across the Jeep bend. The short extension piece bump strap will need to be about 5/8 in. off the bend to accommodate a heavier bend around the rear corner panel.

IMPORTANT Before placing the bump strap to the Jeep, do an alignment check. 1 3/4 in. from the bottom of the door seal to the top of the bump strap is a good location.
Take your time with the actual installation. Slowly removing the adhesive as you move along the body of the Jeep, holding the bump strap in place. Press firmly where the tape is removed.

IMPORTANT
Once that tape adheres to the Jeep, it is designed not to come off. Protecting the Jeeps paint and filling the gap between
the Jeep and Step Slider.

Step 14
EXTENSION PIECE PREPERATION
Install the spacer plate between the extension piece and the main body. A small gap is normal until the plate is secured. Bolt the extension piece to the rear of the main body using a 4 5/16 in bolts with washers and nuts. Tighten down the bolts to 18 ft. lbs. or hand tighten securely.

IMPORTANT
Prep your extension piece to the body on a flat surface. That way the face of the step slider body is even on the top and in front.

Step 15 STEP SLIDER INSTALLATION

Starting on the passenger side. Before placing the Step Slider on the Jeep, pull the circuit board (A) and motor connector (B) through the last cutout between the last bolt and the step slider bracket mounting hole. This will make it easy to find your wires and plug in.

When you have the bolts on the step slider

inserted into the pinch seam holes, the Step

A

Slider will stay on the Jeep by itself. Secure

the Step Slider to the seam by using a 1/4 and

5/16 nyloc nut 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 away inside of the step slider for later installation.

Now tighten the pinch seam nuts. 1/4 in. nuts torque 8 ft. lbs. 5/16 nuts torque to 18 ft. lbs.

FREQUENTLY ASKED QUESTIONS:

I just installed my steps and they are not coming down when I open the door.

Double check the connections. Check the fuse to make sure it is plugged in. Is the on / off switch getting power? Is the circuit board plugged in? Are the door sensors plugged in?

My rocker switch is getting power, but the light stays on in both positions.

The light is only supposed to be on when the system is turned on. If it is lit in both positions simply switch the red wires on the back. Will this kill my battery with the light constantly lit?
This will not kill your battery unless you leave it lit for a month with no use.

deploy.

If this works, plug the motor back into the harness. We test each and every motor that leaves

our factory by hand along with assembling your step slider by hand. These may fail, but it is

extremely rare after we send them after having tested them. If you test the motor and all you

hear is a clicking sound but nothing happens, there is likely internal damage.

I tested the motor, and it works. I checked the sensors individually, and the system still won’t work. The steps don’t deploy unless I do it manually with 12V power.

In rare circumstances, the circuit board that runs the system may be faulty. Send us an email at Warranty@rockslideengineering.com to request a new circuit board.

I opened my door a bunch of times and Our systems have built-in protection against quick cycling like this to prevent damage. the system just shut off. What happened? Simply turn your on / off switch to off, wait 5 seconds, and then turn it on again.

on the rear doors as well, you will need to purchase two kits.

The steps deployed and won’t retract. What is going on?

Chances are your magnets are misaligned. To diagnose which door needs to be adjusted, unplug the rear sensors with the front doors closed. If your steps come up, then it was the rear doors that need to be aligned with your magnet. If the step stays down, the front door needs to be aligned. Open your door, shift the magnet in a direction, and shut it again. Repeat until the step comes up when the door is shut. Mark the magnet placement on the front door. Plug the rear door sensor in, shut the rear door and front door, and see if it comes up. If not, the rear door is misaligned (Since we just aligned the front door we know it’s the rear door now). Repeat the previous process of opening your door, shifting your magnet, and shutting your door until the step comes up. It may take a few tries.
OPTION 2
Check the sensors. Unplug both of them from the wiring harness on the side that is not working, and plug one back in. Manually test your sensors by putting a magnet really close (but not touching) to the sensor. Does it make the step retract? When the magnet is away, the step should deploy. If the steps deploy right after installation, more than likely your magnets just need to be aligned. Do this one by one with each sensor by the method above. Install one sensor, test, align the magnet on the door, test, and then mark the position of the magnet so if for some reason they do move out of place you can easily realign them.
