Picked up a kit for my 04 cobra motored GT the other day for cheap. It came with everything but the WOT switch and bottle brackets. I got a set of brackets but the guy says there was no WOT switch, just the bottle, solenoids (NOS and purge), misc wiring and the MSD 2 step switch box. I was reading the instructions and I **think** the box takes place of the WOT switch because it uses a signal from the TPS. Is that correct?

"2 step switch box"? Are you sure its not a launch controller?

The new way of doing it (at least on cars with tps switches) is to use an electronic box that plugs into your tps and activates upon WOT. No more mechanical switches. You just have to figure out if your MSD box is one of those.

For a dry shot on a Ford, you need some sort of way to bump fuel pressure I think, since dry shots on Fords don't spray thru the maf like an LS1. Did all that stuff come with your kit?
 
FUEL
By spraying cold nitrous oxide across the MAF, it tricks the factory computer into thinking there is a lot more air going into the engine. The vehicles factory ECM adds additional fuel to the fuel injectors. At-least thats what the dynotune web site says.

SWITCH
A micro throttle activation switch and mounting bracket should come with this kit. I believe it is the switch in the plastic bag at the bottom of this pick.

Dynotune sells the (tps) micro switch for $69.00

The DynoTune TPS Electronic Nitrous Activation Switch Will allow you to activate your nitrous system without using one of the small micro switches that are prone to water damge and vibration issues.

This Electronic switch simply runs off your Throttle position sensor output (Works on all TPS sensors even the newer GM fly by wire set-ups!

It has an super bright tri-Color LED to indicate when the output is on and its trip point is fully adjustable via a program button. Simple installation and a rugged fully potted enclosure allows you to mount it in the engine compartment and ensures flawless operation.

Its micro package allow you to mount it anywhere (It is smaller than your nitrous relay). It has two outputs, one sends out a 12V source and the other is a wire that is grounded when activated. This feature makes it compatable with all window switches, nitrous controllers, etc.

NOTE: An additional relay may be needed on some installations.

The Kit contains the following:
*DynoTune Programmable TPS Switch and instructions.
