Hi There - Has anyone figured out what the amperage is on the one spare/unused fuse in the passenger footwell fuse box? I want to connect an external battery for my dashcam, and would ideally like to use a fuse that does not have any load on it. Unfortunately, the cover plate does not state anything for that fuse (but it does have power (given the copper coils you can see inside of it, as opposed to the two blank fuses in the top right). Nothing in the manual either. How would one find out what load it can support?
