I am planning on tapping into the interior fuse block to power my Curt trailer wiring. The Curt harness requires that it be wired directly to the battery to have power at all times. The fuse required is a maximum of 10 amp. None of the existing fuses provide these requirements. Are any of the empty slots available for this. In Canada on my CX-3 GX Sport the empty slots are 1 to 4, 6, 9 and 13. Thanks in advance.
