Diode Dynamics Ultra Heavy Duty Single Output 4-Pin Wiring Harness

Reliable Power for Large Light Bars

When you’re running high-output off-road lighting, you need a harness built to handle serious current. The Diode Dynamics Ultra Heavy Duty Single Output 4-Pin Wiring Harness is engineered specifically for multi-pod SS5 CrossLink Pro setups and long Stage Series light bars—delivering clean, stable, and protected power straight from your vehicle’s battery.

Key Features

• Powers 5–8 pod SS5 CrossLink Pro Light Bars and SS30/SS40/SS50 Stage Series light bars

• Designed for high-demand setups with 10AWG high-capacity wiring

• Direct battery connection for maximum reliability

• Single Deutsch DT-P output connector for UHD Splitter Harnesses

• Integrated 60A waterproof fuse and 80A 12V relay for system protection

• Includes a three-way switch (backlight / off / main beam) and Aux Switch Bank adapter

Heavy-Duty Performance You Can Trust

This harness is built for one purpose: safely powering large, high-output LED light bars. With thick-gauge 10AWG wiring and a dedicated DT-P connector, it provides a stable, efficient power path capable of supporting up to 45 amps of auxiliary lighting. Whether you choose to run the included switch or tie it into your vehicle’s factory auxiliary switch bank, installation is plug-and-play and straightforward.

Each SS5 Pro pod draws 6.7A, so when you’re running 5–8 pods—or using a 30”+ Stage Series bar—this harness ensures everything runs safely, smoothly, and consistently.

Compatibility You Need to Know

This UHD harness uses a DT-P size output connector, meaning it’s designed to plug into the Ultra-Heavy-Duty SS5 Splitter Harness, not directly into individual Diode Dynamics LED products. It’s purpose-built for multi-pod CrossLink Pro configurations and long-format Stage Series bars.
