Hi, I am also trying to set up the clutch switch for launch control but on a Plugin ecu on an RB25 skyline. The functionality i understand ... but i dont seem to have a clutch switch input pre-wired. The switch is fitted to the car but does not seem to be connected to a digital input. Do i need to re-wire into a currently fitted input? or is there an input in there for the clutch switch already that needs activating? Thanks
