Controling a 12 V Throttle body servo motor

Thanks for the advice but i am far from a little child. Nothing is going to be in the engine bay anyway. The throttle pedal will remain where it is meant to be, under my right foot, and the throttle body where it was meant to "live" too, in the hood. The controller is the whole thing. I would apreciate it if you could help with this project.

It's PWM driven btw
