Hey guys, new user here. Just installed a ZEX wet 75 shot kit onto my 08 350z. I want to install a window switch so I don't activate too low or accidentally damage something when I hit the limiter. I saw the Summit Racing/ Intellitronix Switch online and this is the one I plan to use. Currently, the ZEX kit is wired based upon their instructions, and it works correctly. I made up this wiring diagram on how I believe the window switch should be wired in, but I'm not 100% sure it's correct. If someone could check over it and ensure it is correct, it would be much appreciated! Also, if there's an easier/better switch or method to use, please let me know.

PS
Which wire on the coil am I looking to tap into? The Positive, Negative, or the multicolor one?
