What does the yellow ground output wire go to?

Also is there a way for me to test the nitrous before I actually spray the car with the controller?

Only way I can think of is to have someone basically rev the car car in neutral and see if any spray comes out after the nitrous solenoid.

Forgive my ignorance I am pretty green when it comes to nitrous.

Edit: I guess I better post my set up first

Dynotune Universal Dry Kit
Harris Speedworks Purge
Harris Speedworks 4 button switch panel
Harris Speedworks bottle heater ( on its own circuit)
Dynotune single stage RPM window switch

Thanks for the help in advance

 

I don't remember what the yellow wire connects to, but when I was testing mine, i held the lines that was suppose to go into the manifold and had someone rev and tell me when it was at xxxx rpm so I know that it was spraying at the right time. So yes, you can test it that way to make sure that it is firing at WOT and at the correct rpm.

 

I think I have everything hooked up right. Except for the yellow wire. I do not have a clue where it is to go. And the wiring diagram does not tell me. I will post a link to it.

Looks like the yellow is not used unless your adding accessories, the yellow looks like a enabler that would ground an accessory controller to function it with the spray.

 

The yellow wire is the second stage, just roll it up and zip tie off

 

Awesome guys thanks. I have it all hooked up right then!

 

SINGLE STAGE RPM WINDOW SWITCH

Yellow and orange are the color of the wires (for stage one and two) on the Dynotune TWO Stage switch

Anybody knows where the coil wire is suppose to go the dynotune single stage?? # 1 spark coil pack? Or what? Stumped...please help, thanks!! Forgot something else to that I have a question about... the Blue wire to the WOT switch input and the pink to the relay that also goes to the WOT wire, is that right? Or can I just splice the blue and pink together to the WOT wire?? Thanks again!

 

Alright now I know where the tach/coil wire goes, but still lost about the pink wire to the relay then the blue wire to the WOT wire switch, because its the same wire!! Trying to get car done for the track later today to test out a 100 shot! Any help would be awesome! Thanks!

 

Here are the instructions for it if you don't already have them.

They are pretty clear on what goes where unless you have some additional interface boxes to hook together.

Anybody has any problems with the motor reving at high in idle with this window switch, throwing this code- "P0507 Idle air control system RPM hight then expected"... do I need to change my TPS sensor, or whats going on? Thanks for the help...
