AEM Water/Methanol injection kit hook up to s300

[element]

well just wanted to make sure since im not 100% witch wire should i run to a relay then to a pin out on the ECU so that i can also control the meth module from s300, since the AEM kit is controlled from the amount of pressure then it will activate.

let me know what i should do here is a diagram of the wires.

or how you guys hooked it up to s300.

The only way I can suggest hooking it up is hooking the arm switch to a nitrous output that way you can set the conditions at which it comes on and then set the changes to fuel an ignition you want to use.
