You may already have that wire in place, that fat orange one in your photo with the female spade connector housing. Trace it back and see once you have the kick off.
The fuse box breaker is a little harder to find, it's a 12V 40 amp self resetting breaker with plug in adapters for the fuse holders. Manual reset breakers are easier to find, but a bit of a pain if you ever have to reach under the dash to reset it. Check around with local electrical supply houses and auto electrical repair shops, they may be able to source one for you.
