Nilight ATV/UTV Fan Override Switch Kit 16AWG Relay Harness Waterproof Illuminated Rocker

Nilight's 16AWG ATV/UTV Fan Override Switch Kit is a plug-and-play relay harness and illuminated rocker switch that lets you manually control your vehicle's radiator fan without cutting factory wiring.

If you need a simple way to stop or start the radiator fan on an ATV or UTV while parked, stuck in mud, or during trail-side maintenance, this kit provides a low-profile, waterproof switch and a heavy-duty 16AWG relay harness for reliable operation. The system is designed to be installed quickly by tapping into the fan connector and powering the switch from a 12V source, preserving OEM wiring and avoiding complicated splicing.

How does the override kit install on my ATV or UTV?

Installation is intended to be fast and reversible: the harness uses a T-plug that mates with the fan connector so you don't have to cut factory wiring. The kit includes a 5-pin illuminated rocker switch, relay, blade fuses and cable ties to secure the routing.

• Insert the T-harness into the vehicle fan plug for a plug-and-play connection
• Connect the switch power lead to a 12V source and ground
• Mount the waterproof rocker switch in a panel or dash opening
• Use included cable ties and fuses for secure, protected wiring

Will this relay harness work with my model of UTV?

The harness is compatible with many popular ATV/UTV models but excludes certain 2019 four-seat variants. Check vehicle fitment before buying to ensure connector and relay compatibility with your fan circuit.

• Compatible: Polaris RZR (many models), General (most years), Ranger, Sportsman, XP and 1000 variants
• Also fits: Can-Am Defender, Maverick X3, Commander, Sport and Trail models
• Also fits: Kawasaki MULE, TERYX; Honda TALON, PIONEER; Yamaha YXZ

What are the reliability and durability features of this switch kit?

Nilight built the kit with reinforced plastics and waterproofing to withstand off-road conditions, vibration and exposure to water or mud. The illuminated 5-pin rocker switch is easy to locate at night and the 16AWG wiring and relay provide a robust path for fan current.

• Durable reinforced plastic housing resists wear and impact
• Waterproof switch design with transparent blue illumination
• 16AWG wiring and relay sized for typical radiator fan loads
• Includes blade fuses to protect the circuit from overloads

How does using an override switch help during off-road use?

Manually controlling the fan can prevent unwanted operation when you're submerged or sitting in deep mud, reducing debris intake and avoiding unnecessary battery draw while stationary. It also gives you a quick way to stop the fan for maintenance or to keep it from spinning when the engine is cold.

• Stops fan while vehicle is stuck in water or mud to limit debris ingestion
• Prevents fan from running unnecessarily when parked, conserving battery
• Makes routine checks and repairs easier without disconnecting factory wiring

Who is this for: Off-road enthusiasts, fleet mechanics, and trail riders who want a clean, reversible way to control the radiator fan on their ATV or UTV. If you want a non-destructive install, a waterproof illuminated switch, and a relay harness built for rugged use, this Nilight kit delivers straightforward control and protective components for many popular off-road vehicles. Confirm your model compatibility before purchase to ensure correct plug fit and avoid the listed 2019 exceptions.
