The great thing about trailer brake magnet wiring is that it's not polarity sensitive which means that either wire can be used as the power or the ground. So as long as one of the wires on your trailer is power for the brake output circuit and the other is ground it would not matter which would attach to which on the magnets as long as the other wire matched correctly.

I attached a link to a page on trailer wiring with diagrams for you to check out as well.
