tmiller, do you have a 23SS or a 233S? there's no 233SS.
as for your lights, it sounds like you may have crossed the wires putting the battery in, resulting in the resettable fuse/breaker going.
check the wiring, along the tongue, just back from the battery, for a little fuse block. should have a button on it.
pretty common mistake, there's lots of similar posts that owners did the same thing.
