I'll ask my brother about it, cause im sure he wired it all up. he might be willing to help wire yours up or give you some info. I'll ask him and let you know.
edit: spoke to my brother about it. Wiring it up isnt that hard its just setting it up. You basically have to do street driving to get it set up correctly. Its awesome for holding boost, whatever level you set it at it will hold it, but when it comes time to up it more it can be a pain. If you want it at one level i would suggest leaving it at that.
