I just got a ZEX wet nitrous kit with the new purple box that has everything built into it. It supposedly reads the throttle position off some wire and I need to know how to get a reading off the TPS for the purple box to read. For those of you who have installed nitrous before, please let me know some pointers in getting this installed. My friend and I are installing this next Saturday and we both never installed a kit before however are aware of the dangers. Please help me out with some info on the electronics end. Thanks. I'll post pics and dyno once installed.
