The elctro-valve is located under the chassis, just above the fuel thank, about 10-20cm towards front of the car. I manged to get her from
here but it's possible from under the car too. Just follow the flow hose (the one from the right of the car). You can also track the wires who connect to this valve.
...Any cable? I used something like
this. That is not the starter, is a start/stop solenoid. Don't confuse them.
