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

The ATOLS 12V 500A pre-wired winch solenoid contactor kit is a plug-and-play control system that gives reliable remote and wired control for 9000–13500 lb ATV and UTV winches.

This complete winch control bundle combines a heavy-duty 500A solenoid relay, an upgraded control box, wireless remotes and a corded hand controller so you can install and operate your winch quickly without complex wiring. All internal wiring is preassembled and the kit arrives with jumper cables, a negative lead and clear instructions so it’s ready to connect to most 12V winches in the 9000–13500 lb range. The control box housing has been reinforced for weather resistance and durability to protect critical components in outdoor environments.

How does the pre-wired design speed up installation?

The relay and control box come with factory-installed internal wiring, reducing the steps needed for setup. Instead of assembling multiple terminals and routing individual wires, you only attach the provided quick-connect jumper cables and the negative lead to your winch and battery.

• Preassembled internal wiring in relay and control box
• Comes with four quick-connect jumper cables and a negative wire
• Clear instruction manual streamlines hookup
• Plug-and-play approach cuts installation time and errors

Will this relay handle high-load winches reliably?

The 500A solenoid contactor is built for heavy current and engineered to maintain consistent conductivity under load. Precision contacts and robust internal components reduce the chance of voltage drops or interruptions when pulling heavy loads.

• Rated 12V, 500A for 9000–13500 lb winches
• Precision-engineered internal contacts for stable signal transfer
• Durable construction resists wear from repeated engages
• Designed to work with ATVs, UTVs and similar vehicles

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

The kit provides two wireless remotes and one corded hand controller so you can choose remote convenience or a hardwired, fail-safe option. Wireless remotes are useful for stand-back operation, while the corded hand controller is ideal when you need guaranteed contact and precise control near the winch.

• Two wireless remotes for line-of-sight, hands-free control
• Corded hand controller for direct, wired control at short range
• Receiver module included and preconnected to the control box
• Combination gives redundancy and flexible use cases

How does the control box protect the relay and electronics outdoors?

The control box housing has been thickened and upgraded to improve resistance to moisture, dust and aging. That protective enclosure helps maintain long-term electrical performance even when exposed to dirt, rain and vibration common in off-road use.

• Reinforced, corrosion-resistant control box housing
• Improved waterproofing and dustproofing features
• Quality materials chosen to reduce aging and degradation
• All accessories built to match the control box durability

Who this is for: This ATOLS kit is aimed at ATV and UTV owners, off-road enthusiasts and service technicians who need a reliable, high-capacity control solution for heavy-duty winches. It suits operators who want fast installation without extensive rewiring, require both wireless and wired control options for safety and redundancy, and prefer a rugged, weather-resistant control box to protect the relay and electronics during outdoor work or recovery tasks.
