Can't figure out launch control

My launch control only works in neutral, regardless of clutch input. Does nothing in gear.
I've unplugged the neutral switch from the tranny and that just disables any input to the ECU. Right? How does unplugging the neutral switch help anything? I've read how I might have to wire the neutral switch wire to the clutch switch inside the cabin, which I did (I think). and still nothing. What's the clutch switch? There's 2? What color are the wires? What's the wiring I gotta setup?

Personally, i never had this problem in my na6 chassis.
if you have to rewire it to the clutch switch, i would assume it would be the bottom (closest to the firewall) because it triggers when the clutch goes in at all, whereas the top (closest to driver) triggers when the clutch is pressed all the way.
so if you set up flatshift, it doesn't let go of the rev limit until the clutch is fully engaged again.

Neutral switch ties in with the clutch switch, you want them separate since MS doesn't use the neutral switch for anything. The clutch switch is the one touching when the clutch is released, the one with small wires. Wire colors depend on the chassis, give more information or look up a wiring diagram. Check continuity at the ECU connector to ground when the clutch is depressed. Can't help you with MS stuff since we don't know what kind you have.
