For the trailer wiring you have now you'd need to match all of the colors to the standard 4-way wiring colors except the red would go to yellow as that's only color that's different. This would be the left turn/stop signal.
Normally white is ground, brown is taillight, green is right turn/stop, and yellow is left turn stop.
