after seeing it being done its pretty easy.... wiring is too easy. for the solenoid, 1 goes to the actuator on your tarbin and the other goes to the pressure line... in my case, the pressure line was tapped into one of the carbon cannister lines.
when you get it going, make sure you set the duty cycle at aboot 40% so you dont boost to 2bar or something....unless your tarbin can handle it....
