Add-a-Fuse with Fuse

The Add-a-Fuse is a component used to connect electrical devices in the fuse box of the Tesla Model S (after 2016) and the Model X.

It is placed in the position of an original fuse. This fuse goes into the lower position of the add-a-fuse, and the supplied fuse goes into the upper position. This way, the original circuit remains intact, and the accessory to be connected is also fused.

You have the choice to connect the accessory to a constant or switched power source.

Therefore, nothing changes on the car, and everything can be easily and invisibly restored to its original state.
