Pre Drill hole at center of slot marking with an 1/8”
Drill and then drill to 17/32”. Then insert the rivet
nut (18) into position. Refer to install card in rivet
nut tool bag.
Warning: Rivet nuts not properly collapsed will
not hold securely to sheet metal.
Repeat steps 1 through 8 on the passenger side.
Use forward most hole for marking Rivet Nut
location.
Reinstall front linkage just snug, using the 2 Hex
bolts.
Slide the motor assembly (4) onto drive shaft and
mounting bosses of front linkage assemblies (2).
Use two Hex bolts (12).
Mark the center of the forward most slot for the rivet
nut hole. Once done then remove linkage.

Front Linkage
Install the Conical bolt in the installed Rivnut. Use
Shim(22) between linkage and rivet nut hole. Line up
Conical Washer bolt (20) to Shim (22) through slot, as
shown below.
(Motor Linkage)
Before installing motor to front linkage, mount linkage
to the second set of holes of the pinch weld from the

Installing Electrical Components
Route the long wire harness leg along the top of the rewall and
then down away from the steering shaft and exhaust to sub frame
then back to pinch weld area. The other leg shall go along the
Fuse box, then down away from the exhaust and to the pinch weld
area. Zip tie as needed.

Use a lubricant on the two purple wires provided with the wire harness (7). Starting from the passenger
lower compartment feed each wire thru the grommet up to the engine compartment. Make sure to feed one
wire at a time, and pull wires careful to prevent grommet from coming out.

Now using an 1/8” drill bit, drill a hole in the specied area shown
below. Make hole bigger by using a 9/32” drill bit.

Note: It is very important to add the
grommet, as damage may occur if
wires get stripped from rubbing on the
sharp metal of the hole.

Now, feed the tube (25) thru the lower/center of the
dash.
Pull down carpet on dash lower/center on
the driver side and pull the tube through from
passenger side. Note: When feeding tube
thru, make sure to position it under exist-
ing wire harness (see picture) to keep the
wires away from the silver AC/Heater tubing
as that part may get hot and cause damage
to wires. Once the tube is fed thru, feed both
purple wires thru the tubing tool.The tube can
now be pulled off.
Feed wires thru the under dash cover as shown to keep wires tucked up out of the way. Connect the OBD II
plug to the trigger wires with Posi Lock Connector (14). Connect the matching wire color/stripe.

Harness. Attach matching colors on the harness to the wires on the module. Plug in module to
OBD II port on the vehicle. Secure harness with supplied tie wraps. Note: If the OBD II pass thru har-
ness (76404-01A) was purchased see install sheet supplied in packaging. The pass through harness allows for
an open port for other accessories. See below for a brief description.

Check that all doors activate the Power Step and the LED Lights work when doors open
and close. Reinstall any remaining trim panels.
CORRECT OPERATION OF LIGHTS: All four lamps will illuminate upon opening any door of vehicle. Lamps
will stay on until restowing of both Power Steps or until 5 minutes has expired with the doors open. When the
lights timeout after 5 minutes, they can be reillumintated by closing and opening any door of vehicle.
FINAL SYSTEM CHECK
Check that all doors activate the PowerStep and the LED lights work when doors open and close.
NORMAL OPERATION: When the doors open, PowerStep automatically deploys from under the vehicle.
When the doors are closed, PowerStep will automatically return to the stowed/retracted position. Note that
there is a 2-second delay before the PowerStep returns to the stowed/retracted position.
Reinstall fuse.
Reinstall fuse.
Check for Power

Automatic power deploy:
The running boards will extend down and out when the doors are opened.
Automatic power stow:
The running boards will return to the stowed position when the doors are closed. There will be a 2-second
delay before the running boards move to the stowed position.
Automatic stop:
If an object is in the way of the moving running board, the running board will automatically stop.
To reset, clear any obstruction, then simply open and close the door to resume normal operation.
Manually set in the deployed (OUT) position for access to the roof:
your foot while at the same time closing the door. To resume normal operation, open and close the door.
Maintenance: In adverse conditions, debris such as mud, dirt, and salt may become trappedin the running
board mechanism, possibly leading to unwanted noise. If this occurs, manually set the running boards to
Avoid spraying the motors directly. After washing, apply silicone spray lubricant to the hinge pivot pins.
Do not apply silicone, wax or protectants like Armor All® to the running board stepping surface.
Caution! Keep hands away when the running board is in motion.
