The nitrous solenoid is in the center of the pic at the top. To the left of the red/black wiring. Its black and wrapped with the ground wire i believe.
THere is nothing wrong with the kit but i prefer the zex kit personally. I think the price is nearly the same also. ALot of users have used it with great succes.
