MotoControl Bi-Xenon: 9007/9004

The Morimoto MotoControl 9004/9007 Bi-Xenon Relay Harness is the ideal solution for powering HID systems with the stable voltage they require for maximum performance and reliability. While factory headlight circuits are designed to power standard halogen bulbs, HID ballasts demand a consistent power supply. The MotoControl harness delivers clean battery power directly to your HID system, eliminating flickering, startup issues, and voltage drops that can reduce lighting performance.

Stable Power for Maximum HID Performance

A relay harness is one of the most important components of any HID conversion or projector retrofit. By drawing power directly from the vehicle's battery instead of relying solely on the factory headlight wiring, the MotoControl harness ensures your HID ballasts receive the steady voltage they need for reliable ignition, consistent brightness, and long-term durability.

Advanced 8-Pin Relay Technology

Morimoto's third-generation 8-pin relay features an integrated capacitor that stores electrical energy during switching between low and high beams. This eliminates interruptions caused by brief signal gaps found on many modern vehicles, ensuring smooth and uninterrupted operation of Bi-Xenon projectors without flickering or ballast shutdown.

The upgraded weather-sealed relay connector also provides significantly improved reliability and protection against moisture, dirt, and corrosion.

Universal Vehicle Compatibility

Unlike many standard relay harnesses, the MotoControl is designed to operate with both positive-switched and ground-switched headlight circuits. This universal design makes it compatible with virtually any vehicle, whether old or new, simplifying installation across a wide range of applications.

True Plug-and-Play Installation

Installation is fast and straightforward with no cutting or splicing required. The harness plugs directly into your factory headlight connectors while supplying power directly from the battery through heavy-duty wiring and integrated relays. Extra-long wire lengths allow installation on compact cars, trucks, SUVs, and larger vehicles.

Perfect for:

• HID Conversion Kits
• Bi-Xenon Projector Retrofits
• Morimoto H1, H80, and other Bi-Xenon projector systems
• 9004 and 9007 headlight applications

OEM-Quality Construction

Built to Morimoto's premium standards, the MotoControl harness features abrasion-resistant Techflex braided sleeving to protect the wiring from heat and wear. The relay is housed in a durable anodized aluminum enclosure with laser-engraved branding, providing exceptional durability while maintaining a clean OEM-style appearance under the hood.
