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.

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.

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.
