BMW E9X 3 Series M-Sport Fog Light Conversion Harness — OEM-Style Plug & Play Retrofit Cables for Non-M to M-Sport Fog Lights + Front Bumper Conversion | E90 Sedan, E91 Touring, E92 Coupe & E93 Convertible

Upgrade your BMW the right way with our M-Sport Fog Light Conversion Harness, designed specifically for owners converting from a standard Non-M front bumper setup to M-Sport fog lights. When switching to the M-Sport bumper and fog light configuration, the factory wiring on Non-M models does not directly match the bulb connector used by the M-Sport fog light housing. This harness solves that problem cleanly and correctly.

Built for a true plug-and-play retrofit, this conversion harness connects directly to your factory H11 fog light wiring and converts it to the HB4 connection required for M-Sport fog lights. That means no cutting, no splicing, and no messy wiring modifications. It’s the proper way to complete your bumper conversion while keeping the installation clean, reliable, and reversible if needed.

Each harness is made to provide a secure connection and includes waterproof seals to help protect against moisture, corrosion, and long-term electrical issues. Once installed, it allows your M-Sport fog lights to function properly with your factory wiring system while maintaining an OEM-style fit and finish.

Whether you’re doing a full front-end conversion or simply replacing damaged components during an M-Sport swap, this harness is an essential piece to ensure your fog lights install and operate correctly.
