Do you have a volt meter?
The illumination control module through the brake relay module is the source for the right rear brake light. Check the black wire with a yellow trace at the ICM with the brakes on. If you have power the only thing left is vehicle wires and the socket. the black with red trace is the left and the black with blue trace is the center brake light.
