Ok so here is the deal, i bought a car with a nitrous kit and everything is done except the wiring.

I have a wet kit with purge so i have 3 noids, fuel, nitrous and purge. The car is tunned for nitrous alread and has been used a few time but the guy i bought it from ripped all the wires out. I have the msd digital window switch, and a dynotune lean shut down switch i need to wire in.

I am supposed to be getting instructions emailed to me on the dyno tune switch.


Here is what i need to know. were do i need to start i have 2 wires off each noid so basicly i know theres a positive and ground on them, the msd box i have has a normally closed switch output and a normally opened switch output. I have no idea what them are for but the rest of the wires i do.

Basicly any help were i need to start at would help greatly.

 

Damn.. Start by getting a relay switch and connectors and wire cutters..

 

got all that, to arm a system the switch will go to the relay wich will swap over and what is powered when armed?

 

basicly the purge and bottle heater will be its own circut so i can turn it on before the system is armed. so that is done........

the system being armed would direct power to the fuel and nitrous noid is this correrect? or will that have to be wired in with the msd outputs that i dont no what they are?

 

by the way im not going to use conectors i will soilder it in

 

look at the diagrams in my sig link....bet there is something pretty close to what you need

 

i will check it out, thanks ray

 

Set the MSD box to activate/supply power at your set rpm or time. Figure out the 12v output wire for the MSD and run that into two wires on your solenoids.

Ground the other two wires from your solenids. These grounds would go to a fuel safety switch if you have one.

The arm button gets 12v and goes to the input side of a relay. When armed, this would activate your MSD box to pull timing.

Purge could be ignition switched 12v

Lots of different ways to wire one up depending on your electronics and relays.

What type of MSD box is it? If it is a timing twister, it requires power all the time and your wiring setup would be different. Especially how you arm the system.
