Step 1
Starting on the driver side, locate the five
mounting locations underneath the vehicle.
This installation will use the first, second,
fourth and fifth mounting tabs.
Note: Each bracket is specific to a mounting
location. Refer to page 1 product image for
correct locations.
Step 2
Starting at the front driver-side mounting
location, locate the threaded hole on the
inside of the body panel and place an
L-bracket on to that panel.
Attach one standard mounting bracket to the
L-bracket and vehicle using an M8 hex bolt,
flat washer and lock washer.
Attach the pinch weld with a 5/16" flat washer
and nylock nut. Attach a step bracket using
two 7/16" hex bolts, two 7/16" lock washers,
two 7/16" flat washers and two 7/16" hex nuts.
Snug the hardware, but do not fully tighten.
Repeat this step for the
second mounting location.
Step 3
Locate the fourth mounting tab from step 1.
Insert an M8 clip nut through the access hole
and align it over the adjacent smaller hole.
Secure an L-bracket and middle bracket to the
vehicle with an M8 hex bolt, lock washer and
flat washer.
Attach the pinch weld with a 5/16" flat washer
and nylock nut. Snug the hardware, but do not
fully tighten.

Step 6
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 5
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.
Step 4
Locate the fifth mounting tab from step 1.
Insert an M8 clip nut through the access hole
and align it over the adjacent smaller hole.
Place an L-bracket on to the body panel.
Attach one standard mounting bracket to the
L-bracket and vehicle using an M8 hex bolt,
flat washer and lock washer.
Attach the pinch weld with a 5/16" flat washer
and nylock nut. Attach a step bracket using
two 7/16" hex bolts, two 7/16" lock washers,
two 7/16" flat washers and two 7/16" hex nuts.
Snug the hardware, but do not fully tighten.

Step 8
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 7
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 9
On the front passenger-side mounting
location, locate the threaded hole on the
inside of the body panel and place an
L-bracket on to that panel.
Note: On models with def tanks you will not
attach to the threaded hole on first mounting
location.
Attach one standard mounting bracket to the
L-bracket and vehicle using an M8 hex bolt,
flat washer and lock washer.
Attach the pinch weld with a 5/16" flat washer
and nylock nut. Attach a step bracket using
two 7/16" hex bolts, two 7/16" lock washers,
two 7/16" flat washers and two 7/16" hex nuts.
Snug the hardware, but do not fully tighten.
Repeat this step for the
second mounting location.
Step 10
Repeat steps 3 and 4 for the third and fourth
mounting bracket locations.

Step 12
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.
Step 11
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 13
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 15
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 16.
Step 16
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 15 on
the passenger-side of the vehicle.
Step 14
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 15.
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 16.

Step 18
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 17
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.
