The wires are big enough to handle 1 amp, in my opinion. I, on the other hand, wired mine direct to the battery with a 10 amp fuse and its holder right at the battery. This powers the Wolo horn and allows a battery charger to be plugged into that outlet. Number 12 insulated wire, red. This setup eliminates a lot of heartburn. De dee put a fuse holder inside the glove box which was genius! These .2 amp fuses hidden under nearly impossible to remove bodywork had to be designed by a committee.
