    And when they are no electricity did the module reset or it keep his position ?

    Just to help provide a better ground...

    Not, used in this application... It's basically an 'off' override that bypasses the button...

    It will reset to 'off' thus why I suggest hooking it up to an always on +12V...

    You can but it will default to 'off' with every car restart...

    Whoops missed that on the drawing, I have updated it...

    Use a 1N400x (1N4001, 1N4002 etc) rectifier diode, mind the polarity aka the silver band...

    Take a picture... Do you have a load on the output? Are you using the correct voltage range?
