First thing I would do is ask your buddy what all he messed with, if you can get him to undo the damage he did to your trailer you will be in better shape. It sounds like the original problem you had was just a bad ground on the passenger stop/tail light. Typically light assemblies ground through their mounting hardware so ensuring this light is attached to a clean metal surface would be a great place to start and would most likely fix the problem.

I attached a trailer wiring diagram for you to check out as well.
