Hi Gabriele, soory, I didn't see your message before now. My PSE setup uses what is called a "latching relay." This kind of relay holds power on or off each time it is switched, so when you pust the button, it keeps the valves open, until you push the button again. Go see my wiring diagram again, a regular relay won't work, it must be a latching relay. Good luck! http://986forum.com/forums/boxster-general-discussions/50649-homemade-pse-version-1-0-done-behold-evan-sport-exhaust-pics-vid-writeup-%3D.html

Ciao Evan,

i follow your instruction for "home made PSE button" but I have this problem:

- The switch work just if I push it continuously. When I stop to push the button, the valve change the status (from open to closed).

Can you help me in found the solution? Where is the mistake?

Thank you in advance. Best regards

Gabriele
