ARK 12 Pin ECU Trailer Harness Plug with Reed Switch – LED Compatible for Non-CANBUS Vehicles (SKU: AHP12)

The ARK AHP12 ECU Harness Power Connector is a smart solution designed for vehicles that experience trailer lighting problems due to advanced vehicle electrical systems. Many modern and European cars emit pulsed current for diagnostics, which can conflict with LED trailer lighting, causing flickering, flashing, or even total failure of the lights.

This 12-pin harness is fitted with an integrated ECU filter to stabilize current output and ensure seamless LED compatibility. In addition, it features a built-in reed switch that detects when a trailer is connected and automatically disables reverse parking sensors—so you’re not annoyed by endless beeping when backing up your trailer.

Key Features:

• 12 Pin Automotive-style Trailer Plug
• Built-in ECU to eliminate pulse current interference
• Compatible with LED trailer lights
• Reed switch disables reverse sensors when connected
• Ideal for most vehicles NOT using CANbus systems
• Reduces lighting issues and error signals on dashboards

Applications:

• Caravans, campers, trailers with LED lights
• Vehicles with reverse sensors
• European or modern vehicle models with complex electrical systems

Whether you’re a DIY installer or a seasoned tow expert, this 12-pin harness delivers a dependable interface between your vehicle and your trailer—without the headaches of flickering LEDs or constant reverse beeping.
