Control light bars and more from the cabin
Connect your in-cabin controls to the AuxLink sender, then operate accessories connected to the receiver without routing an individual control wire through the firewall for each one.
Keep accessory wiring in the engine bay
Mount the receiver near the accessories and their power connections. This keeps the high-current wiring under the hood, where the equipment is installed.
Skip the extra runs through your firewall
The sender communicates with the receiver across the vehicle, reducing the bundle of accessory control wires that would otherwise need to pass between the cabin and engine bay.
