ATOLS 12V 500A Pre-Wired Winch Solenoid Contactor Kit for 9000–13500 lb Winches — Dual Wireless Remotes & Corded Control

ATOLS 12V 500A pre-wired winch solenoid contactor kit is a ready-to-install control system that lets you operate 9000–13500 lb ATV and UTV winches using two wireless remotes and a corded hand controller.

This complete control package bundles a heavy-duty 500A solenoid contactor, a reinforced control box, a wireless receiver, dual wireless remotes, a corded hand controller, and all necessary jumper and ground cables for a true plug-and-play winch upgrade. The pre-wired internal connections reduce installation time and lower the chance of wiring errors, while the ruggedized control box adds protection against dust, moisture, and outdoor wear.

How does the pre-wired design simplify installation?

The kit arrives with the relay and control box already assembled and wired, so you attach the provided jumper cables and negative ground cable to your winch and battery. This removes the need to splice heavy-gauge wires or map individual terminals, making setup faster and less error-prone for DIYers and mechanics alike.

• Pre-assembled relay and control box—no internal wiring work needed
• Includes four quick-connect jumper cables for standard winch terminals
• Comes with a negative ground cable and clear instruction manual

Will this relay handle heavy winch loads?

The solenoid contactor is rated for 500 amps and built for sustained conductivity under high load cycles, suitable for winches in the 9000–13500 lb range. Its engineered internal contacts minimize voltage drops and reduce heat build-up, supporting reliable performance during demanding recoveries.

• 500A heavy-duty relay for high-current winch systems
• Precision contacts designed for reduced electrical resistance
• Matches common 12V winch power requirements for ATVs/UTVs

What control options are included and when should I use each?

The kit includes two wireless remotes for flexible, remote operation and a corded hand controller for secure, close-range control. Use wireless remotes for stand-back recoveries or coordinating with helpers, and switch to the corded controller when you need uninterrupted, line-of-sight-free control during tight maneuvers.

• Two wireless remotes for convenience and range
• Corded hand controller for reliable, interference-free operation
• Receiver unit pre-wired to the control box for quick pairing

How durable and weather-resistant is the control box?

The control box housing has been reinforced with thicker materials and treated for corrosion and aging resistance, helping to shield the relay from moisture, dust, and outdoor exposure. All included accessories are manufactured to match the box’s durability so the kit performs consistently in rugged conditions.

• Thickened, corrosion-resistant control box housing
• Sealed design for improved water and dust protection
• Sturdy remotes and wired controller built for field use

Who is this for: This ATOLS kit is aimed at owners of ATVs, UTVs, and light trucks who need a robust, easy-to-install control solution for heavy-duty winches. It’s particularly useful for backyard mechanics, off-road enthusiasts, rental fleets, and anyone upgrading an older winch controller to a safer, higher-capacity relay with multiple control modes. If you want a plug-and-play upgrade that reduces installation complexity while adding wireless and wired control flexibility, this kit fits the bill.
