Here is the mystery piece in question.....

if no one here can figure it out, email a pic to Nitrous outlet... I bet they would know.. I have no idea, never seen anything like that..

As Larry mentioned, could be a fly by wire WOT switch. Did the guy you bought it from possibly have a car with an electronic TB?

No idea what car this was actually ever on. But if you look at the picture, you can tell whatever this box is, its brand new.

Window switch?

[sman]

Nope thats the MSD box.

Nope thats the MSD box.

Lol I know, I owned it. They make window switches that aren't digital.

No other ideas? Im guessing its a TPS box, to use instead of the WOT switch. Would be great if this was the case, as the WOT switch is really the only ugly part in the engine bay.

You can run it off the accelerator pedal

looks like a NX tps switch

OK, so im 99% positive its a TPS switch (which is awesome) but every brand I look up (including NX) looks different and doesnt have the same color wires.

On an aside. My origonal plan was to hit it with a 100 shot, but kinda want to do a 125 if the fuel pump and bottom end are up for it. (Thoughts/opinions?)

Working on a wiring diagram right now, will post it later (if im ever happy with it) for critiquing.

Hope to be doing some of the install tomorrow if anyone wants to come by and help out


Also, for mounting the bottle in the spare tire area, what additional bracket-ry is required? Just put a plate in that area to make it flat and bolt it down?

Id be willing to help, not sure how much help I would be haha..give me a heads up though and Id come on out

[sman]

I will let ya know Rolo, no set time or anything, need to do some cleaning in the barn first.

Finished wiring diagram, N2O gurus please have a look. Does not include purge, sort of ran out of room, but its just a simple circuit, not worried about it.

ALSO, I am not sure on the TPS switch wiring. I have not been able to find out what brand that switch is so what each wire color does, is totally unknown to me.

125, no problem. I wouldn't hesitate to spray 200 on a stock bottom end just have to know what your doing.

[hoogiesngrinderz]

At first glance (with zero knowledge of digital MSD/TPS switches) you need to see if the yellow wire from the MSD (or "pink" wire from TPS) sends a positive voltage or grounds the circuit. If they both send +12v or both ground, nothing is going to happen.

I don't, but Phil does, lol.

What about fueling? Is the stock pump good for 125 or 150?

[DETROITMUSCLE]

its borderline, should be ok for that size shot but I would be looking into a racetronix kit as a future mod just to be safe.
