Fuse sizes and the type of Fuse Taps vary depending on your vehicle, please check your Fuse Box to see what type of fuse tap your vehicle requires. There are 4 variations of the add-a-fuse that we carry: ACZ(micro2), ACS(mini), ACN(LP-mini) and ACU(ATO) as photos (2 Needed Per Vehicle). Complete Accessories - Contains all the components required to easily piggyback on the fuse box of any vehicle. Simply plug the required fuse tap cable into the vehicle’s fuse box to provide the camera with its own power supply. Low Voltage Protection - The inbuilt minimum voltage limiter will protect the vehicle's battery from going flat. If the voltage of your car battery drops to this default voltage 11.8V or 23.6V, it will cut off the power, which leaves you with enough power to start your car for the next time.
