⚙️ Bracket & Motor Installation

Install Front Bolt Plate

Locate Driver Side Front Mounting Points

●Locate Driver Side front mounting points on the rocker panel under the front door. Remove any OE plastic insert caps.
●Insert the Bolt Plate (J) into the upper left hole, ensuring bolt threads face the frame.
●Use the plastic retainer (F) to secure the bolt plate in place.
●TIP A pry-tool is recommended for removing plastic insert caps.

Pre-Assemble Brackets

●Take the mounting brackets and attach them to the linkage arms.
●Insert M8 Carriage Bolts into the square slots on the brackets, with threads pointing downwards.
●Fasten the aluminum linkage arms to the brackets using M8 Flanged Nylon Lock Nuts (4 fastening points per bracket).
●NOTE Tighten the M8 Flanged Nylon Lock Nuts all the way until tight.

Mount Front Bracket

Front Bracket Mounting Point - Perspective from front

Front Bracket Mounting Point - Perspective from back

●Line up front mounting bracket slots to the rocker panel threaded inserts.
●Place the Driver Side/Left Front Bracket Assembly (A) onto the rocker panel.
●Fasten using 8mm Bolts, Lock Washers, and Flat Washers into the OE inserts, and an 8mm Hex Nut to the Bolt Plate.
●NOTE Do not tighten all the way yet. Adjustments may be needed later.

Mount Rear Bracket

●Locate rear mounting points and remove appropriate plastic OE insert protectors.
●Line up bracket slots to studs and place Driver Side/Left Rear Bracket Assembly (B) onto rocker panel. Remove any obstructing rubber plugs.
●Fasten using 8mm bolts (K), lock washers (L), and flat washers (H). Do not fully tighten yet.
●NOTE The more forward pair of inserts are additional mounting points (not on all vehicles). If present, use them for extra strength. If not, use just the rearward 2 mounting points.

⚡Power & ECU Setup (Engine Bay)

Battery & Power Connection

● Remove Fuse: Open the front hood. Remove the 25A fuse from the main harness fuse box.
WARNING Do not skip this step to prevent electrical sparks and shorting.
● Power Leads: Connect the Positive (Red) lead to the positive battery terminal, and the Negative (Black) lead to the negative terminal. Ensure both are secure.
● Connect ECU: Connect the ECU (P) to the main harness.

Routing & ECU Mounting

● Route Harness: Route the main harness down the Driver-side wheel well. Route the shorter leg down the Passenger-side wheel well.
Avoid contact with moving or hot engine components. Secure with supplied cable ties.
● Mount ECU: Use the 5 included double-sided adhesive tapes to secure the ECU. Secure it near the battery or any space away from direct engine heat.

Cabin Routing (Standard Models)

For most standard models

● Access Grommet: On the underside of the Driver Side, locate and remove the floor grommet in the floor panel behind the front linkage arm.
● Thread Wires: Poke a hole through the grommet and thread the two signal wires up into the vehicle cabin.
● Inside Cabin: Remove the driver-side front kick panel and bottom door sill plate. Peel back the carpet to locate and pull the wires through.

Cabin Routing (Specific Models)

ONLY FOR: 22+ Silverado 1500 & 24+ Silverado 2500/3500

● Reroute Harness: For the specific models listed above, route the signal branch of the main harness through the Passenger Side instead of the Driver Side.
● Locate Cap: Find the plastic cap on the underside of the passenger side floor panel.
● Penetrate: Poke a hole using a drill or punch through the plastic cap to feed the wires into the cabin.

Motor Connection

● Attach Harness: Attach the main harness (M) to the LED Y-Harness (N).
● Connect Driver Side: Attach the LED Y-Harness (N) to the motor on the Driver Side.
● Connect Passenger Side: Repeat the process for the Passenger Side.
● NOTE The shorter LED Y-Harness should connect to the motor that is on the same side as the ECU.

🔌Deep Dive: Signal Wiring Guide (BCM Connection)

Step 10: Determine Your Technology System

Pre-refresh System (Follow Part A below):
19-21 Silverado/Sierra 1500 & 20-23 Silverado/Sierra 2500-3500 HD.
22 Silverado 1500 LTD & 22 Sierra 1500 Limited.
Post-refresh System (Follow Part B below):
22+ Silverado/Sierra 1500 & 24+ Silverado/Sierra 2500-3500 HD.

Part A: Pre-refresh Technology System

Locate OBD-II Port

● Locate: Find the OBD-II Port under the steering wheel, near the front hood release lever.
● Access: Unbolt the two bolts using a socket for easier access to the rear side of the plug where the wires are located.

OBD-II Connection Guide

Signal	Factory Wire	Main Harness
CAN LOW	3rd from right (lower)	Yellow
CAN HIGH	3rd from right (upper)	White

Note: On some vehicles, wire colors may differ. Rely on the pin position. After connecting, return the module back into its place and tighten the bolts.

Part B: Post-refresh Technology System

Locate Radio Module

● Locate: Under the glove compartment on the Passenger Side, locate the radio module.
● Access: On some models, the underside shield may need to be removed to access the components.
● Identify Plug: Determine your radio type by looking at the two main connectors.
If you have a GREEN and GREY plug, follow B-1.
If you have a BLACK and GREY plug, follow B-2.

Radio Connection Guide

B-1: GREEN and GREY plug

Pin 16 = Blue w/ White Stripe (Connect to White). Pin 4 = Blue w/ Yellow Stripe (Connect to Yellow).

B-2: BLACK and GREY plug

Pin 9 = Blue w/ White Stripe (Connect to White). Pin 10 = Blue w/ Yellow Stripe (Connect to Yellow).

Signal	Factory Wire	Main Harness
CAN HIGH	Blue/White Stripe	White
CAN LOW	Blue/Yellow Stripe	Yellow

Note: On some vehicles, the positions of the plugs may be reversed. After connecting, return the module back and tighten.

Part C: General Wire Taps Guide

How to use "Shark Taps"

● Clamp: Take the wider end of the tap and wrap the jaws onto the vehicle data line. Clamp jaws tightly.
● Insert: Insert the Power Step Main Harness signal wire into the narrow jaw.
● Secure: Clamp the jaw tightly. Needle-nose pliers are highly recommended to ensure the metal blade pierces the insulation of both wires to make a proper connection.

⚠️ CRITICAL NOTE:

Make sure the wire is seated properly in the jaws before clamping. The wire being tapped must be centered on the "teeth" to make a proper tap. If wires are not fully secured, use a screwdriver to pry open the buckle, wrap the broken part with electrical tape, and re-do the tapping process.

🔩 Final Assembly

External Connections

● Install LED Lights: Peel the adhesive backing and stick the LED lights to the rocker panel underside. Plug them into the harness.
● Connect Harnesses: Under the vehicle, connect the Main Harness to the LED Y-Harnesses on both sides.
● Plug in Motors: Connect the Y-Harness to the front motor plugs.

Mounting the Boards

● Power Up: Re-insert the 25A fuse.
Open the door to extend arms.
Unplug the motor to cut power and keep brackets down for installation.
● Mount Boards: Slide (4) M6 Carriage Bolts into the channels. Align with bracket slots. Secure with Washers and Nuts. Adjust position and tighten all nuts.
● Reconnect: Plug the motor connector back in (or re-insert fuse). Close the door to retract the steps.

✅ Final System Check

Cycle Test: Open and close each door multiple times to ensure the steps deploy and retract smoothly without binding.
Check Hardware: Double-check that all mounting bolts are tightened to spec.

It’s fully automated. The boards deploy when the door opens and retract when the door closes. We use advanced CAN bus technology to read door signals directly, eliminating the need for unreliable magnetic switches.

Absolutely. They are built for it. All components, including the IP67-rated motor and connectors, are weatherproof and sealed tight. They are tested from -40°F to 176°F to ensure flawless performance.

We built them strong! Each side has a proven load capacity of up to 660 lbs. Feel free to load up your gear or stand side-by-side with a buddy—they can take it.

Yes. The 6-inch wide platform features an aggressive textured surface designed to provide maximum grip, even with wet or muddy boots.

Yes, there is! Integrated LED lighting automatically illuminates the step surface when the board extends, dramatically improving visibility and safety for those late-night entries.

Safety first! Our boards include an auto-stop anti-pinch function that instantly halts movement if an obstruction is detected. Plus, there’s a 3-second safety delay before retraction just to give you extra peace of mind.

Nope! That’s the beauty of them. When retracted, the boards fit snugly against the vehicle body, ensuring you maintain your maximum ground clearance for optimal off-road capability.

No drilling required. This is a 100% bolt-on installation. Our brackets utilize the designated factory mounting points on your truck’s frame. Check out our installation video above for a detailed walkthrough specific to your vehicle.
