Nitrous Related Wiring

[CAT3]

Feel free to search thru the diagrams, instructions and write-ups and use at your discretion and risk. I am not an electrical guru so I cannot attest to the validity of any of the diagrams, HOWEVER, we have quite a few genius' here and I am sure if there are any diagrams that are not correct, missing vital pieces etc they will pm me so I can remove them. I sure there is more than one way to wire stuff up, but some if may not be safe, and that is my goal, to provide our community with the RIGHT way to wire these things up. This is not meant to be a discussion type thread, merely a source of technical information, so please DO NOT POST nontechincal comments. I may end up locking it, so it remains a "technical information" thread only, and doesnt get cluttered up with bs.

I will eventually group diagrams together and clean it up, for now, I'm throwing it together.

When posting diagrams, instruction, write-ups etc, please use the Reply Post and put a description of what its about in the Title: line for ease of searching. Thanks.

Attention

I am slowly cleaning up this thread. It took about 1 ½ hours to do page 1 and 2. trying to get rid of all non contributing tech. That means posts like this one (see missing image below), and one's with dumb questions that will not add tech information. Please, please, send a PM to our new site wiring Guru Ray@Nitrous Outlet and ask him to do a wiring schematic for you. Then when it's finished, you or Chris can post the diagram and explain what's there. We are getting way, way to many posts on this thread. It makes it useless to go through 15 pages of mostly nonsense. If you have any ideas on how to make this thread more productive, just PM me.

Vinny at 860 Performance showed me this trick for wiring on my panels. I was using individual wires for each switch, Vinny suggested Y-ing them from switch to switch.


Here is the "Hot In" to a Arm, Heater and Purge setup

Same way I started the wiring for my big panel with your design. Good post.

All of my diagrams are being changed over to my new site (Comcast is down for my old site), and I will up date the links soon. Sorry about this, but comcast sucks, they say they can't find my site at all, but was working on new site already, anyway.

Here's a 2-stage using a BMN WS with 1st gear lock out, and an MSD WS. This was put together by BMN at my request. Notes are my own.

Here's a link to all of the Timing Resistor Trick Information. It's a pretty complete data base for getting a resistor trick system up to snuff, maybe the most complete on the web, or at least in one place.

EDIT: All info below and more can be found at my web, in the wiring section.

Here is a couple replys from the last 2-days on a often asked question about my home made 1st gear lock out on the trans. If this dosen't make sense let me know and I would be glad to clarify. I don't have it drawn up (hint/hint), and also will add a description on the dual stage with home made lock out when I get a chance.

First description.
Just tap into your wire running to the pedal WOT micro sw. Remember, wire it opposite (you'll need a 3-prong sw from radio hack), meaning when pedal wot micro sw in 1st gear in mashed to the floor and making contact or closed, the 1st gear lock out micro sw on your trans is open. Then when you shift out of first gear the pedal micro sw acts as normal because both sws are now closed, or making contact. This is for a single stage set up. Wiring using this method in a dual stage set-up is a little differnt. Hope this makes sense.
Here is the pic for anyone reading along.


Second description worded a little different.
It's a three prong type WOT micro sw from radio hack. You can wire it inline with standard wot under pedal, but it must be backwards, and thus three prongs instead of two. Meaning, when in 1st gear it will still break the connection going to pedal wot sw and as soon as you shift out of 1st then standard wot sw works as normal. This is for a single stage, and I have mine wired up to keep my 2nd stage out of 1st gear. Hope this makes sense.

Edit: Here's another way to mount sw on the C5. Glued directly onto the rubber isolater, and stock shifter.

I have been asked a bunch of times...

Here is how Vin @ 860 Performance hooked up my Window Switch

This is for a Electronic Throttle Controlled (ETC) C-5 Corvette



Tach and TPS connection

The tach wire was hooked up to the Coil Pak








TPS wire



STEP 1. TACH set-up

0 0 individual coil packs

STEP 7. TPAS Mode
0 2 = TPS signal

STEP 8. TPS WOT setting
Note: only applies if Step 7 is configured as 02
B.C = WOT voltage
While at IDLE, press switch #2 to read and display the TPS signal. Pop the throttle to open it all the way – the unit
only needs to see WOT for a fraction of a second. Now press switch #1 to save the displayed value. (You do not
have to be at WOT when you press switch #1 to save)[/quote][/quote]

Once your done check the RPM on the window switch by holding button 1 in.
Pictured below is the car at idle 700 RPM.



Rev and compare tach to what the Window Switch is seeing if it does not match change your settings in step 1 until you see what matches your application.

[00Vette]

Hey Beer? Are you sure the Tach setup (step 1) is supposed to be set to 01=coil packs that fire in pairs (waste spark systems) and the tach wire is connected to the coil?

Because our cars look like an individual coil pack per cylinder. I have the same window swith as you and went with the same tach setup as you! But It don't make sense to me.

Oh, and I got to let Dave know or whoever.......that the provided window switch instructions are just about the worst ever! Way confusing. It took Robert and I quite some time to figure that damn thing out.

[Robert56]

This is from Slowgoat (gotohmy also supplied info), with notes of my own in blue. Hope this helps clarify some issues. This is a single stg wiring, and was used on an '05 GTO. Can use the dual stg FJO wiring diagram and just drop the 2nd stg stuff. Please check this out for errors, anyone (Ricky).

NITROUS SOLENOID
wire 1 - big blue wire on FJO Controller
wire 2 - to 87 on relay (green wire)

FUEL PRESSURE CUT OFF
wire 1 - ground
wire 2 - to 85 on relay (white wire)

RELAY
black - battery positive (constant power)
red - to accessory on toggle switch (arm switch)
green - to wire 2 on nitrous solenoid
white - to wire 2 on fuel pressure cut off

FJO CONTROLLER
(window switch and progressive)
big black - ground
big red - n/a (used for a 2nd stg trigger or two ramp rates)
big blue - to wire 1 on soleniod
(harness)
black - ground (common ground)
white - acc. of toggle switch (arm sw)
white/red - throttle position wire (green wire on throttle body)(TPS)
(small) red - n/a (trigger wire, for trans brake, 1st gear sw, to run the two different ramp rates on a single stg)
green - tach signal (green wire passenger side coil pack)

TOGGLE SWITCH
3 prongs
power - ignition (switched power)
acc. - to white wire of controller & red wire on relay)
ground - ground

While we are at it, program settings are to be as follows (TPS) Falls RPM multiplier x 2

I hope this can be used by others so they don't go threw the mess I did...

Edit: here is some info on the tach and TPS wiring for the '04 and '05 GTO. Info (almost quoted) from NX Ricky.
04 GTO LS1
TPS wire-at the throttle body BLUE wire. at the computer pin 24 grean seal connector 2. blue wire
TACH coil trigger wire-light green passenger side connector, at the computer pin 10 green seal connector 2. brown wire


05 GTO LS2
TPS wire-at the computer pin 31 green for falling black connector. TPS at the throttle body Green wire
Tach coil trigger wire-light green passenger side connector. At the computer pin 48 blue connector 1 Brown wire I believe..

Will be adding to this list as I go through my notes. If anyone has some info for this list just pm me and I'll credit ya if ya want.

Edit to post #40
the last line should say (X 2) not divide 2

"While we are at it, program settings are to be as follows (TPS) Falls RPM multiplier /(divide) 2"

Question?,
Do you have to have two activation switches for a dual stage setup?
Reason why I ask is because I run a NX switch panel and there is nowhere
to hook a second stage.

No, many ws on the market now have dual stage capability. When I put mine together there was none, so two sws for me. Actually a WS and RPM activation sw.

more common on lt1 guys but anyone use the mallory 685 hifire ignition...
http://www.jegs.com/webapp/wcs/store...tegoryId=18101
also uning this 121-8876 from jegs...it connects to the wire harness to the coil, and i know how to hook it up the the mallory box...
im ordering mine monday and my wet kit will be here tuesday so i should be hooking it up later next week...some1 have a similar diagram for that...or scratch one up? lol
this box uses a built in timing retard, window switch, and revlimitor along with start retard controal
i hear you can wire it only to be active when you arm it...this will pull timing and leave optimal performance when not using nitrous...
can anyone help
