I just recieved my NX Gemini Stage 6. It came with a nitrous solenoids with 3 ports. One in the bottom and one on both sides. Is this solenoid a "Iceman Solenoid"? Does the bottom port go into the brass hardlines? On one side it is labeled "in" and on the other side it is labeled "P". Where do I mount my purge? On the "in" side with a purge manifold or on the "P" side? The instructions isn't clear. Also, What purge solenoid comes with the Genx-2 kit? THANKS, PEACE 1
