Help finding PWM input on ESC

Got the esc and motor from an old skateboard, would like to convert it to arduino control. Is anyone familiar with this esc and know if there is any way to connect the pwm input to it? there are two connectors that is not used on it, one with 4 inputs and one with three inputs, the center pin on the 3pin connector is grounded and the two center pins on the 4pin connector is grounded.

No. Don’t . Lol

I wouldn’t spend too long on that before deciding to use a different ESC for the purpose.

One of your friends invited you to hit the road using the skateboard you kept under your bed. And you thought of upgrading your old Build Kit boards to make your trip more fun and thrilling but don’t know how to. In this case, I suggest using the best electric skateboard kit.
