If it's a dry kit, it's a fairly simple install. Like said before you tap your intake and put your nozzle in there. You should only have one selonoid, if its dry, and to wire it you take one side and put it to a good ground. The other side you would want to run to a relay. The relay should then run to a throttle switch, to a constant power, and to a ground. The the throttle switch should run to a arming switch inside the car, which will run to a keyed 12 volt. Mount your bolt brackets, and connect your nitrous lines, and your good to go.
