[QUOTE="Juiced-03, post: 876706, member: 9715"] I hope you are prepared to open up the Zex box to modify a few things. If so then read on. You will need a small allen wrench to remove the screws on the zex box (four on each side) and take off the cover. Then you will see the solenoid. You will see two big black wires coming out of the solenoid. Cut those two wires at the point where it meets the other wires. You can also remove the circuit board inside the box. It only control the wide open throttle activation and you wont need it. You WILL have to use a push button operation swithc on this Zex kit since you wont be able to use the TPS to control wide open throttle. I like the push button method myself anyways. So basically once you have the wires cut off the solenoid, route them through the hole on the Zex box. There should only be two wires coming out that hole. One will be a ground and the other will be a power wire for the solenoid. Now you have the wiring taken care of. Hopefully you know how to rig up a temporary switch (activation) with an arming switch. If you dont know I will explain that too, but I am assuming you know the basics of wiring. Now once you have the Zex box put back together, you will need to buy two small rubber caps to be put over vacuum line outlets on the Zex box. Place the caps over these two nozzles and secure them with small hoseclamps. The nozzles I am talking about are right next to the outlet for the nitrous nozzle that goes to the intake. You wont need those because their only job is to raise the fuel pressure on the regulator that the 03 cobra doesnt have. Now you can buy jets from NOS which is what I did.
