GMURA Pre-Wired 12V Winch Control Box Kit — 500A Solenoid Contactor, Wireless Remotes (2) for 8,000–17,000 lb Winches

GMURA's Pre-Wired 12V 500A Winch Control Box Kit is a ready-to-install solenoid contactor system that simplifies wiring and adds wireless remote control for winches rated 8,000–17,000 lbs.

This kit combines a heavy-duty 500A solenoid contactor, a protective ABS control box, pre-installed wiring harnesses and two wireless remotes to make winch installation and operation faster and safer. Designed for ATVs, UTVs, SUVs, trucks, boats and trailers with 12V winches, the assembly reduces on-site wiring work while protecting electrical components from dust and moisture.

How does the pre-wired design speed up installation?

The control box arrives with the wiring harness already connected so you avoid mapping and soldering multiple leads. You only attach the provided jumper cables to your winch and battery, which significantly reduces installation time and potential wiring errors.

• Pre-connected harness: no complex wiring diagrams to follow.
• Four jumper cables included (three 15.7" and one 61" 4AWG).
• Quick-connect lugs simplify battery and winch connections.

Will the 500A solenoid handle heavy-duty winches reliably?

The 500A solenoid contactor is engineered for high current flow and precise internal contacts, enabling stable operation under heavy loads. Precision manufacturing improves conductivity and reduces the risk of contact wear or current interruption during repeated pulls.

• 500A capacity suited for 8,000–17,000 lb electric winches.
• Robust internal contacts for consistent electrical performance.
• Built to tolerate frequent high-load switching with lower failure risk.

What protection does the control box provide for mine and my winch?

The housing is molded from impact-resistant ABS plastic to keep moisture, dust and debris away from the relay and electronics. That protective shell helps extend component life in outdoor and off-road environments where dirt and corrosion are common concerns.

• Durable ABS enclosure resists aging and corrosion.
• Sealed layout minimizes dust and moisture ingress.
• Compact design mounts discreetly near your winch or battery bank.

How flexible is the wireless remote control and receiver?

The kit includes a wireless receiver and two handheld remotes that let you operate the winch up to roughly 150 feet away, improving safety and convenience. Remote operation keeps you clear of the winch line and vehicle while positioning or recovering loads.

• Two remotes included for multiple operators or a spare.
• Approximate 150-foot remote range for flexible positioning.
• Receiver integrates into the pre-wired control box for simple setup.

Who is this for: The GMURA Pre-Wired Winch Control Box Kit is intended for vehicle owners, off-road enthusiasts, boaters and fleet technicians who want a plug-and-play solution to manage medium- to heavy-duty 12V winches. If you need to reduce installation time, protect critical relay components from the elements, and add remote control capability without complex electrical work, this kit provides the key parts: a 500A solenoid, weather-resistant box, receiver and two remotes, plus four 4AWG jumper cables ready for immediate connection.
