Will this harness work with my existing factory wiring?

This harness is designed to work standalone with aftermarket fog lights. If you're tapping into factory wiring, test the polarity and amperage draw before connecting—your vehicle's service manual will specify safe limits for auxiliary circuits.

Do I need additional relays or fuses?

Most fog light setups benefit from a dedicated relay and inline fuse to protect your wiring and vehicle's electrical system. Check your fog light manufacturer's specs for recommended amperage, then size a fuse and relay accordingly.

Where do I mount the switch?

Switch mounting location depends on your dash layout. Test-fit the harness routing first, then decide between dash pod, A-pillar, or steering column—wherever it's within comfortable reach of the driver.
