Possibility in adding vibrate function in Devo12S

I have modded my Devo 8S successfully, just thinking if I can mod the Devo 12S with the vibrate function as well. Any ideas in how to make the vibrate hardware connected to the main board?

Sorry, I can't help you,...........but you could help me
I just inquired about the 8s vibration mod. Is it supported by standard builds. That's what the "enable-haptic=1" is for in hardware.ini? It connects to pin 83, right? Thanks, and sorry.

Actually, I am not sure if there are any unused pins in Devo12S that can be used to work out a vibrate mod, is there anybody who know the hardware of Devo12S can help a bit?

At least make it vibrates alongside with buzzer?
