Fitment

Installation & Warranty

Vehicle-specific fitment. Installation takes about 60–90 minutes with no wire cutting and no programming. One-year warranty. OEM/ODM and regional distribution supported.

What is in the kit

Every kit ships complete: left and right running boards, two drive motors, vehicle-specific mounting brackets (six-point on heavier trucks), the main harness, a controller, the hardware pack and bilingual warning labels.

Installation

Running board installation takes around 90 to 120 minutes. Fit all brackets loosely first, check that the board sits level and parallel to the sill, then torque. Route the harness along the factory loom path and keep it clear of exhaust and suspension travel.

Why this application

Hatchbacks and wagons take a power liftgate cleanly because the factory body module already broadcasts the release and lock signals the controller listens for. Nothing needs to be coded, and the factory remote keeps working alongside the added switch.

Where this vehicle sells

This application is common in Southeast Asian markets including Thailand, Indonesia, Malaysia and Vietnam, where the vehicle is sold in volume and where accessory demand for electric tailgates and running boards is well established. Kits ship with bilingual warning labels and an English installation manual as standard, which is what local installers and insurers expect.
