LLNSEAUTO Universal 2-Door Power Window Conversion Kit — 12V Motors, 3-Switch Wiring Harness

LLNSEAUTO’s Universal 2-Door Power Window Conversion Kit converts manual crank windows into electrically driven roll-up windows with all required motors, switches, wiring, and mounting hardware.

Replace your hand crank with a complete electric window system engineered for two-door vehicles. This kit bundles two DC motors, three wiring harnesses, three rocker switches, mounting plates, adapter shafts and brackets, plus templates and installation accessories so you can retrofit sedans, pickups, SUVs, vans and off-road rigs that originally came with manual windows. The components are designed to operate at 12 volts, include thermal overload protection, and deliver up to 23W output for stronger lift force and improved heat dissipation.

How does this kit turn a crank window into a power window?

The conversion replaces the original manual crank and linkages with electric motors and a regulator assembly that drive the window up and down. You mount the supplied motors to the door, connect the adapter shafts to the window regulator, and wire the switches into your vehicle’s 12V electrical system using the included harnesses and templates.

• Two 12V DC power window motors with thermal overload protection.
• Three pre-terminated wiring kits and three switches for driver and passenger control.
• Mounting brackets, shaft adapters, cover kits, and templates for precise installation.
• Installation instructions and a manual crank instruction for reference.

What vehicles and setups will this conversion kit fit?

This universal kit is built for two-door vehicles originally equipped with manual roll-up windows. It is compatible with many sedans, pickups, vans, off-road vehicles and sport utility rigs as long as the door cavity and regulator geometry allow motor mounting and shaft adaptation.

• Designed for 2-door vehicles with manual windows.
• Compatible with common regulator styles using shaft adapter kits supplied.
• Works with 12V vehicle electrical systems (operating range ±2V).
• Check door cavity space and regulator type before ordering for fitment confirmation.

What performance and safety features are included?

The motors are rated for 12 amps and provide up to 23W of power for improved lifting ability compared with basic conversion sets. The design includes thermal overload protection to reduce the risk of motor damage from prolonged stall conditions and features parts intended to enhance heat dissipation during heavy use.

• Working voltage: DC 12V with ±2V tolerance for common vehicle systems.
• Working current: approximately 12A and maximum power output up to 23W.
• Thermal overload protection to protect motors from overheating.
• Included spacer and mounting kits to help distribute load and reduce wear.

What comes in the box and what do I need for installation?

The package contains nearly all mechanical and electrical components required to finish a two-door conversion, along with templates and installation guides. You will still need basic tools and may require vehicle-specific fasteners or small trims removed depending on door construction.

• In-box items: 2 motors, 3 wiring kits, 3 switches, 2 mounting plates and templates.
• Also included: 2 shaft adapter kits, 10 motor mounting bracket kits, 2 cover kits, 1 spacer.
• Tools required: screwdrivers, sockets/ratchet, electrical crimping or solder tools, and trim removal tools.
• Minor vehicle-specific parts (clips/fasteners) may be needed in some doors.

Who this is for: This conversion kit suits DIYers and professional installers who want to upgrade two-door vehicles from manual to power windows without sourcing multiple parts. It’s ideal for owners of older sedans, trucks, SUVs, vans and off-road vehicles who need stronger motors, thermal protection and a full wiring/switch solution. If you prefer a factory-like upgrade with comprehensive hardware included and are comfortable with door disassembly and basic electrical work, this LLNSEAUTO kit delivers a complete retrofit option with a one-year warranty and a satisfaction guarantee.
