Define "short." Is it sparking badly, AKA drawing a lot of current?
Or is it a "poor connection" AKA your dome light lights dimly, goes out, etc?
Very very first thing I'd suspect is the fuse link/ bulkhead connector
It's very useful to refer to the simplified MAD diagram on their modification page, as it has a simplified diagram of the main power distro

Another good candidate for a short (high current) is the alternator output connection. It is normally no 12 or 10 black with a ring terminal. You may have forgotten it, or there may be something wrong with your alternator
