Like Teejay said, the kit will include its own solenoid and all hoses and wiring required.
Its definitely easier to set it up properly if you have someone that knows what they're doing to help you.
A dyno is the safest place to set it up as air fuel ratios can be checked while the boost is adjusted.
Factory boost cut is 16psi on your car so you wont be able to go above that without replacing your
ECU with an aftermarket one, as I don't think your model can be flash tuned if thats your car in your avatar. Or you can fit a boost cut defender, which also needs to be set up properly.
