The turn signal works, the reverse lights work, and the top third brakelight work.

Lift the the rear seat on the drivers side to access the rear fuse panel. In this panel, check the FPRK fuse LR PRK fuse and the RR PRK fuse.
Customer: replied 2 years ago.
Tested the the necessary fuses and it shows that Im getting power out of the fuse box but still no power to them brake-taillight!

If you have voltage at the fuses, but none at the taillight connectors then you have an open in the circuit between the two. I would start by checking the connectors at the rear fuse panel first. If the connections are okay then I would visually inspect the wiring harness for any breaks.
