Can anyone help with wiring/nitrous install? Please!

Mike Souslin · 06-04-2002, 05:08 PM

Hey guys. It's been a while but I am finally back to wrenching on the stang. I just bought the ZEX nitrous kit. I had done quite a bit of research and decided on this kit. My question in this.
I bought an MSD RPM activated window switch to turn on and turn off the flow of Nitrous at specified rpm's. The instructions on the window switch note that you must use a relay if the amps are more than 1.5??? If anyone can help me with the proper install of this switch and relay I would greatly appreciate it.

Thank You!

I'M running a remote switch for the bottle, another for purge, and another to activate NOS, Im using a timing retard box(msd) 6 deg. ret. that only activates when the solinoid has power to it. But im carbed with a micro switch that activates at only wide open throttle

Here is what I had:
Arming switch wired off the fused side of the lighter fuse connected in series with RPM window switch and throttle switch connected to low voltage side of relay.

Purge run off this switch also.

20 amp fused line dirrect from battery to input side off relay output sied of relay direct to solenoids.

Get some terminal blocks to make the wiring easier & different color wire so its easy to trouble shoot.

isn't the ZEX kit a "smart" kit. What I mean doesnt it only operate when conditions are right? i.e fuel pressure, rpms, etc?
