Finally got around to wiring up my window switch everything seems to be working fine except my rpm's are not matching my cluster??

I tapped into the green wire on the throttle body for my tps



And the white wire behind the cluster for the rpm's, this might be my problem might have to tap into an injector wire.

 

Go to the blue wire on the driver side coil pack harness. Might have to switch it to 4 cyl I can't quite remember.

 

I'll look when I get home and see if I can figure it out.

 

Pretty sure I had to set my boost controller as a 4cyl for it to work on mine.

 

I've been reading on other forums and alot of people said they had to change the number of cylinders and type of ignition to get it close. I'll adjust and get it as close as I can

 

So I figured it out.. for anyone with a silverado around a 2005 installing this switch set the # of cylinders to 4 and type of ignition to dist. Or distributor and it should work almost exact match to my rpms now...

 

Atomic. I wired everything up to the diagram you gave graeme and before I could hear the nx silinoid click when I flipped the master switch now It doesn't do anything what do you think it could be??

 

Do you have the same controller? http://www.nitrousexpress.com/oldweb...ndowswitch.pdf

The way it works is it grounds the blue wire when its activated. I drew it with a fuel pressure switch in there; if fuel pressure drops the switch opens and the solenoids turn off.

The master switch should not flip the solenoids, it just arms the system. The solenoids should only open when 1.) rpm window is met, 2.) throttle window is met, and 3.) there is proper fuel pressure.

 

Yes same controller I'm not running a fuel pressure sensor yet. Maybe that's my problem.

I was just wondering because like I said ,before I put the window switch and purge relay on it would click when I armed the system so it had me worried.





This is my purge switch i can hear lt click in the relay when i turn it on

 

Yeah the nitrous relay and noid will not click until that window switch tells it to do so.
