Pull back the carpet and pull the trigger wires
through the grommet. Seal the holes in the grommet
with silicone sealant.
Access Trigger Wire
The trigger wires are color coded to match the factory door ajar wires. Use the Posi-Taps to connect the
trigger wires to the matching door ajar wires.
DRIVER SIDE
Front Driver Side: Dark Green with Purple stripe. Avoid lighter green wires as these will not work.
Rear Driver Side: Dark Green. Avoid lighter green wires as these will not work.
REGULAR CAB / SUPER CAB: These models do not have rear door ajar wires. Connect this wire to
the constant ground wire (Purple with Black Stripe).
PASSENGER SIDE
Front Passenger Side: White wire found just below flat loom as shown.
Rear Passenger Side: Yellow. The correct yellow wire goes to the back door. Pull up on the yellow wire
that lieads to the back and does not cross over to the driver’s side at the junction. There will be move-
ment of the correct wire near where the trigger wires connect.
REGULAR CAB / SUPER CAB: These models do not have rear door ajar wires. Connect this wire to
the constant ground wire (Purple with Black Stripe).
If you can not find the wire with the correct color you will need to install the motor (Step 13) and test each
individual wire until you find the one that functions correctly.

Mount the Steps to the linkages. Slide the mounting
T-Nut into position. Install M6-1.0 x 20mm Socket
Head Bolts to secure the boards. Use a 5mm Allen
Wrench to tighten the bolts.
Make sure the board moves up and down freely by
hand. If it binds, loosen the linkage to body attach-
ment bolts and adjust the linkage position until the
boards move freely. Do not tighten the bolts at this
time. Tightening the fasteners before cycling
the step several times may create a
bind, causing a squeaking sound and preventing
the boards from retracting completely and
evenly.

attachment screws. Adjust linkages so they
are parallel to each other and the noise is
gone. Tighten all fasteners.
Intermittent operation:
• Wire connections not secure
• Bad ground
• Bad battery connection
Boards operate randomly:
• Wire connections not secure
• Connected to incorrect vehicle wire
Board stays down all the time and can be moved
by hand:
• Gear shaft wedge screw is missing or loose
Board shakes and or shutters during operation:
• Bad ground
• Wire connections not secure
• Bad battery connection
One or more doors operate the board and other
do not:
• Wire connections not secure
PowerBoard Troubleshooting Confirming PowerBoard is functional-black
controller:
To test if the red controller (473.11), wire harness,
motor and lights work, hook up to battery and touch
any of the 4 door trigger wires to + 12V. The board for
that side should go down and the lights should turn
on. The board should go up and the lights should turn
off when the wire is removed from + 12V.
Boards don’t operate correctly when connected
to wires identified in instructions:
Unfortunatelyvehiclemanufactures do notconsistently
keepthesamewirecolorsintheirwireharnesses. The
PowerBoard trigger wires need to be connected the
factory door-ajar wire that is connected to each door
latch switch. The correct wire is likely in the same
bundle that is identified in the instructions. If none of
themworkyoucanlocatethecorrectwirebyremoving
the door panel and tracing the wire bundle that leads
to the door latch.
Useavolt meterortestlighttofindthedoor-ajarwireon
PowerBoardswithredcontrollers.Thecorrectwirewill
go from ground to +12 volts when the door is opened
and return to ground when the door is shut. Connect
onetestleadtothenegativebatteryterminalandprobe
the wires with the other lead. You can use a pin or a
Posi-Tap connector to pierce the wire insulation. The
correctwirewill make the tester gofromno voltage to
positive voltage when the door is opened and return
to no voltage when the door is shut. You can also shut
the door latch with the door open by pushing on the
latch catch with a screw driver.
