Hi everyone I am new here and Im having some issues with the installation of my Zex nitrous kit that I recently bought.

Except for the standard kit I also have these following accessories

Window switch
Remote bottle opener
Bottle heater
Purge selonid
Speed of sound cup holder panel with preassure gauge and four buttons.

The problem I have is that I really dont know how to connect everything and if I need relays and inline fuses and such.

The Cup holder panel has four buttons, first one activates the system, second is bottle heater, third is remote opener and fourth is purge.

Could anyone please advice me on how to connect everything? A simple wiring diagram would really make my day.

Thank you everyone.

Didn't the kit come with wiring diagrams? When I installed the Zex kit on my 2006 many years ago I had full instructions and diagrams.

Do you have a V6 or V8? The window switch is a different between the two because of the waste spark on the 4.0 V6.

spicy

Its a v8, I got instructions on how to install all the stuff like the nozzle,.bottle opener and such but not how to wire everything. What stuff needs relay and if I need inbounded fuses or not.

JimC

Try the Zex website and see if you can download instructions. Even if I could remember how to do it all, I don't think I could put it all in a post easily. I don't recall needing any extra relays or fuses beyond what was in the kit when I did mine.

I have looked at the install instructions but they do not specify what fuse the stuff need. My kit was bought used so I got all the wires in a big lump. And the inline fuses are not in the sockets so I cant look at them either.

This is what i managed to google

Remote bottle opener 25 A fuse
Nitrous management unit 10 A
Heater 30 A
Purge 25 A

If Im wrong on the fuses please tell me.

I also figured out how to wire the opener trough a 8 pin relay or two 4 pin relays to hook it up with the Speed of sound panel instead of the button you get with the kit.

spicy

So I have tried to put together a wiring diagram for the install and I would really like some input on what I have done wrong.

This is my first try ever doing a diagram and actually my first try ever at car electrics at all so please be gentle

Translation of the stuff

All the blue stuff are the Switch panel where I have four buttons

1. On = Arm swit
3. Rensa = Purge
4. Öppnare = Opener

Tändning = Ignition
Batteri = I think you know this one
Säkringsblock = External fusebox (I dont want to splice into the factory stuff to much)
Rensventil = Purge selenoid
TCS = Traction control switch
NMU = Nitrous management unit
Yellow stuff are fuses
Red boxes are relays.
And the black arrows are ground.

Thank you everyone

1. On = Arm switch
2 Värme = bottle heater
3. Rensa = Purge
4. Öppnare = Opener

I left out button number two.

The opener button is a three way switch btw.

Between the two relays on the right to the opener there is a 12v wire that is not attached anywhere, that i supposed to go to the external fuse box and be fused with a 30A fuse.


Anybody have any thoughts?

I'm not familiar with that kit or how it should be wired specifically. But it would appear your bottle opener doesn't have the source 12v based on your diagram, so yes I would think it needs to find a power source on the external fuse block. Other than that it looks like you have everything showing a power source and then a switched 12v activation source.

spicy

Yeah it needs to be connected to the fuse box, I don't know why I painted it like that, must been tired.

Thank you for your input.
