Not likely, but you can trace the wires into the front bezel to see where each ones goes, then draw your own header key for future reference (If it's not labeled on the MB).
You could also try the front panel diagram from ESCs RC410L/800-M. It very close to your board and the FP header looks the same.
If you trace them, compare them to the ESC diagram and let us know if it's the same. That info could come in handy in the future.
