With the Zex kit, do you need the following for best safety? You can't even install these if you wanted can you? That little box does all of these things?

-Fuel pressure safety switch
-Window switch
-WOT switch

I really like the ZEX kit! I'm looking into Nitrous and think the simplicity and ease is really cool. I don't mind the purple either.

 

You need window and FPSS. The box just does WOT switch and has a N20 pressure sensor to adjust fuel. You set the WOT switch off TPS output signal to the ZEX computer.IIRC blue wire of TPS.

 

You would still need a window switch also

After Puting The Zex Kit In My Ls1 98, I Went And Try It Out. But When I Turned It On, And Hit The Gas, Nothing Happen. I Thing It Was The White Wire That Goes To The Sensor. Which Color Wire Does It Go On? I Have It On The Gray Wire (i Think)or What Could The Problem Be?
