So i recently bought a ZEX wet nitrous kit because it is pretty highly spoken of on our forums, but I'm struggling to figure out how to wire it with my Hondata Kpro. I was wondering if anyone could PLEASE help me figure it out. The kit did not come with a relay because the zex "box" is supposed to be able to control when the nitrous comes out, but my tuner says that Hondata should be doing everything for me. ANY help would be greatly appreciated.

 

So you can either use the zex box to control it, or you can omit it and use your Kpro. If you want to go the route of using your Kpro(which is the best way tbh) The red wire is used to arm the system, this can either go to an arming switch or a switched output on the kpro..depends on how your tuner wants it set up.
The white wire is what tells the solenoid to open, this wire will go to a switched output off your Kpro.

If you do not know how outputs work with a Kpro, I'd highly recommend you just pay someone to wire it up for you.

 

The help section in kmanager explains most of the things pretty good.

You have a few choices on input for arming and output pins to activate solenoid

 

Will this let Kpro control literally everything like its supposed to? WOT, window switch, etc.

 

Yes, I can't see any problems or missing functions.
