Question about wiring a window switch with a Zex Kit

[mystictealZ28]

I bought the Zex 82026 nitrous kit for my A4 2001 Z28 and I'd like to run a window switch with it. Zex no longer offers a window switch which is odd because they used to have 82085 but it's been discontinued. I called Zex and they said any nitrous window switch will work but they didn't offer me a wiring diagram. I would like to run the Nitrous Outlet Winmax switch but I was hoping someone could help me with a wiring diagram. The issue I'm having is that all the window switch diagrams show them being wired directly to the solenoids and the zex system I have has the solenoids contained within the nitrous control box. There are only three wires coming from the Nitrous control box, one for 12v of power one for ground and one to read the TPS voltage. Most of the diagrams I have found utilize a standard 30 amp relay but I've yet to find one that illustrates how to wire it up to the zex box. Any help would be greatly appreciated. Thanks! ~Mark

I think I've got it figured out. If anyone could take a look and see what you think. The Blue supplies ground to the relay within desired RPM window. Thanks! ~Mark
