Product Overview
Adding fog lights is not just a matter of plugging two H11 bulbs into the nearest 12-volt wire. Running lamp current through a small dash switch can overheat the switch or wiring, and many used cars have cut or missing fog-light harnesses from previous repairs.
This harness uses a relay so the dash switch controls the circuit without carrying the full lamp load. The H11 lamp connectors make it useful for compatible Honda fog-light setups, but the switch shape and vehicle-side routing still need to be checked because Honda changed dash switches between generations.

Compatibility Notice
This is not a universal plug-and-play harness for every Civic or CR-V. Verify H11 lamp plugs, 12V system, switch dimensions, grounding points and safe fuse/power routing.
Frequently Asked Questions
Why is there a 40A relay in the kit?
The relay allows the low-current dash switch to control the higher-current lamp circuit instead of carrying the lamp load directly.
Will the switch fit every Honda dash?
No. Honda used different switch openings and connectors, so compare the supplied switch to your vehicle before installation.
