Gillian,
It's very possible that the ground wire in the trailer harness isn't
connected. When you are hitched up, you'll get a half-assed ground
through the hitch ball that 'may' make the lights work. You can usually
spot a trailer that's working like this at night because their lights
are flickering with every bump.
Pinouts of the trailer connectors are on
http://www.championtrailers.com, look in the "tech" area.
