Buying Guide

Match voltage and amperage

Confirm the harness supports your vehicle's 12V system and the current draw of accessories (e.g., 180W vs 300W setups) to prevent overloads

Connector and plug type

Choose harnesses with compatible connectors—pulse power or plug-and-play options simplify installation for LED bars and spotlights

Intended vehicle fit

Select harnesses specified for your platform, such as GY6 150cc, 49–125cc engines, or general ATV/quad wiring, to ensure proper mounting and routing

Protection and durability

Look for fused circuits, waterproof relays, and robust insulation to withstand vibration, moisture, and off-road conditions

Ease of installation

Wiring kits with clear terminals, included relays, and labeled leads reduce install time and error for DIY or shop installs
