HD Relay: H1

The Morimoto HD Relay Harness H20 is engineered to provide reliable battery power directly to your HID ballasts, ensuring maximum performance and consistent light output. Factory headlight wiring is designed to power halogen bulbs, which often cannot supply the stable voltage required by HID systems. The H20 relay harness eliminates voltage fluctuations that can cause flickering, intermittent operation, or difficult ballast startup.

Whether you're upgrading your low beams, high beams, or fog lights, the Morimoto H20 delivers the dependable power your HID system needs.

Reliable Battery Power

A quality relay harness is one of the most important components of any HID conversion. By drawing power directly from the vehicle's battery while using the factory headlight circuit only as a trigger, the Morimoto H20 ensures your HID ballasts receive clean, stable voltage for optimal performance.

Benefits include:

• Faster ballast ignition
• Reduced headlight flickering
• Consistent light output
• Improved ballast reliability
• Reduced electrical load on the factory headlight circuit

Easy Plug-and-Play Installation

The Morimoto H20 features a true plug-and-play design with no cutting, splicing, or permanent vehicle modifications required. Its universal layout and extended wiring lengths make it suitable for installation on most passenger cars, trucks, SUVs, and off-road vehicles.

Simply connect the harness to your battery, plug it into the factory headlight connector, connect your HID ballasts, and you're ready to go.

Universal HID Compatibility

The H20 Relay Harness uses industry-standard ballast connectors, making it compatible with virtually all aftermarket HID systems.

Compatible with:

• HID Low Beam conversions
• HID High Beam conversions
• HID Fog Light conversions

Please Note: Vehicles equipped with CANBUS electrical systems or pulsed Daytime Running Light (DRL) circuits may require a Morimoto CANBUS or Mopar-specific relay harness for proper operation.

Dual Relay Fail-Safe Design

Unlike many economy relay harnesses that rely on a single relay to power both headlights, the Morimoto H20 features two independent sealed 40A relays, one dedicated to each side of the vehicle. This provides increased reliability and ensures that one functioning headlight remains operational even if a relay should ever fail.

Each relay includes:

• Fully sealed weather-resistant housing
• Silicone upper and lower weather seals
• Integrated flyback diode for back-EMF protection
• Weatherproof connectors throughout the harness

Designed to withstand moisture, dirt, vibration, and extreme temperatures, the H20 is built for long-lasting reliability.

Premium OEM-Quality Construction

Morimoto uses only premium automotive-grade materials to ensure maximum durability and a factory-quality appearance.

Construction features include:

• Heavy-duty automotive wiring
• Abrasion-resistant Techflex braided sleeving
• OEM-style sealed relay housings
• Stainless-steel relay mounting bracket
• Weatherproof electrical connectors

The result is a clean, professional installation that looks right at home under the hood.
