XBB - Digital Relay Kit 2-Channel + Control Harness

XBB Digital Relay Kit + Control Harness – Easy control for auxiliary lights and larger circuits

This kit combines the XBB Digital Relay Kit with a control harness, giving you maximum flexibility. You can use it as a simple, wireless solution to control auxiliary lights and LED light bars, or as a trigger signal for larger circuits and relays when the load exceeds the XBB unit’s capacity.

With installation via the vehicle’s OBD-II port, you avoid cutting into the wiring harness, and the entire system communicates wirelessly via Bluetooth between the XBB Dongle and PowerUnit. Perfect for modern cars, SUVs, pickups, work vehicles, and heavy trucks.

Features and Benefits:

• Two usage options:
• Direct control of LED light bars or auxiliary lights.
• Use the control cable to trigger larger circuits or multiple relays.
• Quick installation – finished in about 15 minutes.
• Wireless communication via Bluetooth between dongle and powerunit.
• App control through XBB Configurator (iOS & Android) to adjust functions and sync with high beams.
• Safe solution – no error codes, no impact on the vehicle’s electrical system.
• Flexibility – choose to connect directly to lighting or use the control harness for higher loads.

Technical Specifications:

• PowerUnit outputs:

  • Output 1: max 15A (180W at 12V) – LED light bar/auxiliary lights.

  • Output 2: max 5A (60W at 12V) – e.g., position lights or reverse lights.
