Throttle %, brake pressure and ABS?

[Kroggers]

I am looking to include some more data channels to the Racelogic system in my racing car. I have been trying to get the answer by looking at the workshop manual, but could do with some help

I want to record throttle%, brake pressure and ideally also when the ABS activates.

The car is a 2001 Boxster s, so I have the e-throttle. Anyone know what wire at the pedal has the throttle position? I will assume it is a voltage range?

Is there anywhere I can collect brake pressure and ABS activation without having to include additional components to the factory system?

Any help is greatly appreciated...
