Default Launch Control Help

So I'm Having A Little Trouble Wiring This I Don't Understand If It's Just Me Wiring It Incorrectly Or If Its Anything Else.
Basically I Wanted To Setup Flat Foot Shifting / Launch Control.
I Have It Wired Like How I Thought It Should Be Wired, Clutch Wire Cut At From OEM Harness Wired To Switch ( So I Don't Have To Bring Laptop ) Then To ECU. And It Wont Work In Gear It Wont Work In Neutral Either.
I Have A Diagram On How I Have Mine Setup Can Anyone Give Me Any Tips Or What I'm Doing Wrong
Thank You

Wiring

I’ll start by saying you shouldn’t capitalize every word.

secondly, I can’t tell from your diagram what your switch does. You could have it wired right, or you could be feeding 12 volts to your MS or clutch switch. Does it have a light or something?

What are the pins labeled, and what do you have wired to them? That needs to be in the diagram. Im concerned because you drew the input signal in red, like your positive feed.

So Its "Ground" "load" And "12V" I Thought That the load would just be what is being turned on and off.

Most switches switch power. So the “12v” is going to be your ground, load is going to go to the MS, and no point in wiring the ground terminal.

Did it work before you started trying to put it on a switch?

Do you have a multimeter? The continuity function will be real useful here. Also make sure your diagram is correct. The way you have the diagram drawn, the switch doesn't actually cut off the signal since it's tee'd in the line. If you just want the switch to cut off the signal so when it's switched off, you don't get launch control, then wire one side of the clutch switch straight to ground, then the other side of the clutch switch to the middle pin on the switch, then the top side of the switch (or whatever side has continuity with the middle pin when the switch is in the on position) to the ECU input. There should be no 12V involved (unless it's only function is to illuminate a light on the switch).
