HD Relay: 5202/PSX24W

The Morimoto HD Relay Harness is an essential component for any HID headlight upgrade, ensuring your HID ballasts receive a stable and consistent power supply directly from your vehicle's battery. Unlike factory headlight wiring—which is designed to power standard halogen bulbs—the HD Relay Harness provides the voltage and current required for reliable HID performance, eliminating flickering, startup issues, and inconsistent light output.

If you're investing in premium HID ballasts and bulbs, don't compromise with an inferior wiring harness. The Morimoto HD Relay Harness is engineered to deliver dependable performance and long-term reliability in all driving conditions.

Reliable Plug-and-Play Installation

Designed for quick and simple installation, the Morimoto HD Relay Harness requires no cutting or splicing of your vehicle's factory wiring. The universal layout and extended wire lengths make it suitable for everything from compact cars to full-size trucks and SUVs.

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

Universal Compatibility

The Morimoto HD Relay Harness is compatible with most aftermarket HID systems and uses industry-standard ballast connectors, making it suitable for nearly all HID ballasts on the market.

Ideal for use with:

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

Note: Vehicles equipped with CANBUS electrical systems or pulsed daytime running light (DRL) circuits may require a Morimoto CANBUS or Mopar-specific harness instead.

Dual Relay Fail-Safe Design

Unlike many generic HID relay harnesses that rely on a single relay to power both headlights, the Morimoto HD Relay Harness utilizes independent 40A relays for each headlight. This fail-safe design helps ensure that if one relay were ever to fail, the opposite headlight continues to operate, improving safety and reliability.

Each automotive-grade relay features:

• Fully sealed weather-resistant construction
• Silicone upper and lower seals
• Built-in flyback diode for back-EMF protection
• Premium silicone-sealed electrical connectors throughout the harness

Designed to withstand moisture, dirt, heat, and harsh weather conditions, this harness is built for years of dependable service.

OEM-Quality Construction

Every Morimoto HD Relay Harness is manufactured using premium automotive-grade components, including:

• Heavy-duty wiring
• Abrasion-resistant Techflex braided sleeving
• OEM-style sealed relay housings

The result is a clean, factory-style installation that looks as good as it performs.
