KEMIMOTO Fan Override Switch Kit for UTVs — 2-Position LED Rocker, Plug-and-Play Relay Harness

This kit adds a reliable manual override to your vehicle’s cooling system so you can force the fan on during heavy towing, low-speed trail riding, or extreme heat. The harness uses a T-connector and heat-resistant wiring to keep installation simple and reversible, while the included relay and 5-pin rocker switch deliver heavy-duty, weather-ready control.

How does the override switch improve cooling during demanding rides?

When stock fan control won’t keep temperatures in check at low speeds or under heavy loads, the override lets you run the fan continuously to remove heat quickly. It doesn’t modify factory logic — it supplements it, giving you manual authority when you need it most.

• Forces fan on regardless of engine RPM or stock control limits
• Useful during towing, slow technical trails, or hot-climate stops
• Prevents overheating by increasing airflow on demand

What’s involved in installing the KEMIMOTO kit?

Installation is designed to be straightforward: plug the T-harness into the fan connector, attach the power lead to a 12V+ source, and mount the relay and rocker switch in a convenient location. No cutting or splicing of factory wiring is required, and the heat-resistant cables are routed to withstand engine-bay temperatures.

• Plug-and-play T-harness connects to the original fan plug
• Relay pre-wired to handle fan current without additional relays
• Heat-resistant wiring for durable, long-term use

Which UTVs and models are compatible with this switch kit?

The harness fits many popular Polaris and Can-Am models, but there are important exclusions; always confirm your year and model before ordering. This kit supports several RZR, Ranger, Maverick, Defender, and Commander variants but is not compatible with certain recent models listed by KEMIMOTO.

• Compatible with Polaris RZR/Ranger 800, 900, XP 1000 (check fitment)
• Works with Can-Am Maverick, Defender, and Commander families
• Not compatible with 2024–2025+ RZR XP 1000 or 2023 RZR Pro XP models

What does the 2-position LED rocker and relay provide?

The 2-position rocker switch gives two operating modes: factory automatic control or manual override. The illuminated rocker shows status at a glance, while the heavy-duty relay and 5-pin design handle higher current loads safely for dependable on/off operation.

• Position 1: factory mode — original ECU controls fan as intended
• Position 2: manual mode — forces fan to run anytime, even with key off
• LED illumination gives quick visual feedback of switch state

Who is this for? The KEMIMOTO Fan Override Switch Kit is aimed at UTV and side-by-side owners who need extra cooling control for heavy-duty trail use, towing, or operations in hot climates. It’s ideal for riders who want a reversible, no-splice installation and a rugged switch and relay built to withstand off-road conditions. If you need straightforward manual control of your cooling fan without permanent wiring changes, this kit delivers a practical, durable solution.
