Hello,
I would love to just connect the wires from the valve directly to the button in my car but the button is not just an on/off switch. It only sends out a signal to the cars ECU and the ecu activates whatever funcion its supposed to have. That is why i need some control unit for that. Changing the button itself is not an option… i want to use the existing button in the car that has no funcion and the pins from that button are not connected to anything. I know which pin is which.
I know exactly what i want to achieve but its hard to articulate my thoughts as english is not my native language and also which is more importaint, i just started to work with such things as arduino.
