Buying Guide

Confirm vehicle compatibility

Match the harness to your engine and vehicle type (e.g., GY6 150cc, 49–125cc ATVs, go-karts) to avoid plug mismatches or wiring modifications

Check voltage and wattage support

Ensure the harness supports your system’s 12V architecture and the wattage required for accessories such as 180W spot lights or 300W LED light bars

Look for connector types

Connector features like pulse power plugs or plug-and-play headers simplify installation and reduce the need for splicing or extra relays

Assess included components

Verify whether the kit includes relays, fuses, switches, and mounting hardware—kits for auxiliary lighting often bundle these for a complete install

Prioritize build quality and ratings

Choose harnesses from reputable brands with durable insulation, sealed connectors, and strong user ratings to minimize electrical issues in powersports environments
