It sounds like the Curt Tail Light Converter # C56236 will definitely fix your problem. This wiring kit has provisions for a separated brake light circuit and it combines it in with the turn signals like what your standard trailer does. For this wiring kit you'll need to connect the following wires to the following functions:

Brown - Running
Green - Right Turn
Yellow - Left Turn
Red - Brake
White - Ground
Black - 12V Power (pulls power from battery to power trailer lights)
