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, remove two hole plugs.
Insert an M8 clip nut through the access
hole and align it over the adjacent smaller
hole. Insert a second clip nut over the lower
mounting tab.
Place the driver-side front mounting bracket
onto the vehicle and secure with two M8 hex
bolts, lock washers and flat washers.
Snug the hardware, but do not fully tighten.
Step 3
Repeat step 2 for the middle and rear brackets.
Step 4
With the driver-side brackets installed, take
the driver-side running board and insert three
T-rails into the slot as shown.
Note: Position each T-rail as close to the
mounting bracket location as possible.

NEED ASSISTANCE? •844.278.4357 •RA •PAGE 3
Step 5
With help, carefully place the running board
onto the mounting brackets.
Align the T-rails with the mounting brackets
on the vehicle. Slide the top mounting track on
the board over the top flange on each bracket.
Adjust the T-rails in the lower track of the
board so the studs drop into the slots on the
bottom of each mounting bracket.
Step 6
Secure the running board to the front mounting
bracket using one M8 flat washer and one
5/16" nylock nut on each T-rail stud.
Repeat for the middle mounting bracket.
Before securing the rear mounting bracket,
place an LED light bracket over one of the
T-rail studs, as shown in the third image.
Secure each T-rail stud with one M8
flat washer and one 5/16" nylock nut.
Snug the hardware, but do not fully tighten.
Step 7
At this time, adjust the running board
to the desired location.
With the running board in position,
it is recommended to tighten all
brackets to the vehicle first, followed
by the running board connections.
Repeat steps 1 through 7
on the passenger side.

Step 8
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. Route the opposite end of the harness
through the firewall into the cab of the vehicle.
Zip-tie the wiring harness in place
once it is in the desired location.
Step 9
Remove the front and rear door trim
panels on both sides of the vehicle.
Note: Remove any other vehicle components
that could interfere with the wiring harness.

NEED ASSISTANCE? •844.278.4357 •RA •PAGE 5
Step 10
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.

Step 12
If there is no plug in the floor behind the driver
seat, locate a position close to the rear bracket
and drill a 1" hole through the floor of the
vehicle. WARNING: Make sure 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. Continue to step 13.
Step 13
On the passenger side, take the sensor wire
(gray / green) and route it to the front of the
vehicle underneath the carpet.
Take the passenger-side rear actuator
(red / black) and the LED light (pink / tan)
and route it through the floor plug behind the
passenger seat. If there is no plug in the floor
behind the passenger seat, repeat step 12 on
the passenger-side of the vehicle.
Step 11
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.
If there is no plug in the floor behind
the driver seat, skip to step 12.
If there is a plug in the floor behind
the driver seat continue this step.
Take the driver-side rear actuator (red / black)
and the LED light (brown / tan) and route it
through the floor plug behind the driver seat.
With the rear wires inserted through
the floor hole, cut a slot in the floor
plug and re-insert it into the hole.
Skip to step 13.

Step 15
Using the 3/4" x 3/4" double-sided tape, place
the magnet on the door so it lines up with the
sensor. Repeat this for the other three doors.
Step 14
Plug the door sensor into the wiring harness
and route it up the door frame, under the carpet.
Note: Depending on the vehicle, you may need
to use the supplied sensor harness extensions
for the two front door sensors.
Once the harness and sensor are routed to the
desired location, wipe the sensor and door with
the provided alcohol wipe. Place two pieces of
1/2" x 1/2" double- sided tape on the sensor
and attach the sensor to the vehicle.
Repeat this process for the other three doors.
DISCLAIMER: Use of this switch 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 17
Locate a spot to install the power switch.
Drill a hole in the panel with a 3/4" drill bit
and wire into place.
WARNING: Confirm there are no wires
behind the panel prior to drilling.
Important: Be sure to plug the blue female
wires into the silver male ends and the red
female wire into the bronze male end.
Step 16
On the driver side, plug the rear actuator
(red / black) into the running board and
pull the extra wire back into the vehicle.
Plug the LED light wire (brown / tan) into
the LED light and secure it to the mounting
bracket tab with the supplied jam nut.
Once all the wiring is installed, cover the
wires with slit loom for extra protection.
Repeat for the passenger side of the vehicle.
Refer to step 12 for wiring call out.

Step 19
Congratulations on the installation
of your new powered running boards.
With the running boards installed, periodic
inspections should be performed to ensure
all mounting hardware remains tight.
To protect your investment, see the
'Notes and Maintenance' section on
the first page of this instruction manual.
Step 18
Once all wiring is installed, plug in the circuit
board and place it underneath the carpet under
the rear passenger seat.
Attach the two wiring harnesses and
re-install the fuse removed in step 8.

Troubleshooting
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 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.
Everything is plugged in and the
switch is turning on and off, but
the steps still won't deploy.
Two things may be causing this issue:
Check the motor first. Simply unplug it from the wiring harness and apply external 12V power
to the leads. One position will make them deploy. Switch the leads again to make them retract.
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.
Check the sensors. Unplug both of them from the wiring harness, 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. The sensors should have a label with MP###802 or MP###902.
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. Call our product support team at 844-278-4357.
I opened my door a bunch of times and
the system just shut off. What happened?
Our systems have built-in protection against quick cycling like this to prevent damage.
Simply turn your on / off switch to off, wait 5 seconds, and then turn it on again.
This will reset the system and allow it to work normally again.
My running boards are making
squeaking and / or rubbing sounds.
Apply a dry, graphite powder lubricant on each pivot point.
