The Dometic Hard Wiring Kit lets you get power anywhere in your vehicle from your starter battery. It connects power from your in-vehicle starter, to your dual battery, and from there to your Dometic portable fridge/freezer. Perfect for when you need power or a frosty beverage on the go. It uses heavy-duty double-insulated cable for durability, and the rubber caps protect it against moisture and dirt to stop it corroding. The Dometic wiring kit is a great solution for power on the go.
