I am doing a nitrous system and before I install it I wanted to know on the ECU pin out is there a wire for wide open throttle? On our cars we can not use the switch do to the throttle being drive by wire. Thank you. On one page I found it says it is a green wire on terminal number 5. Any help would be great thank you.

 

I've never installed nitrous on a drive by wire car either.
I don't know anything about a WOT wire but you could try looking into a Voltage Switch. Wire it into the pedal or the ECU and set it to around 4.5v, which would be WOT, and the switch turns on the Nitrous. Just an idea.

 

there's a solid green wire coming out of the ecu in the passengers floorboard you can tap. It's the ONLY solid green wire. This one gives something like 4.5V at wide open. Look up the FSM in the ACC manual and look at the ECU pinout. If you need the RPM for a controller, that wire is yellow with Red stripe as well.
