Hey guys, in need of some help. I installed a Zex kit (wet) on a 2007 Nismo and we are having massive issues finding the tach line for the window switch. Ive been in contact with Zex, Nissan, Surgeline, and Zcar garage and still kinda confused. Zex is claiming that you can pull it from the 1st or 3rd cylinders, and use a multimeter to find the correct voltage. The issue with this is that the current isnt steady and thus isnt a good reading for the window switch. I wont run nitrous on this nismo without a window switch, and i'd certainly hate to scratch the $2,300 for parts and labor that ive put into this project...

Any help is greatly appreciated...

Ive already read both those forums, but thanks for trying to help. With the nismo for some reason you cant use the coilpacks from the first or third cylinders like i stated in my previous post. we had Zex call us 3 times and finally stated that on very rare occasions you have to run a tap from an injector to the window switch. It appears to have worked. The only issues is when you are completely off the throttle and de-accelerating the window switch will deactivate. But as soon as you are WOT it will activate again. Hope this helps a few this applies to.

 

Try tapping the ecu.
