Default Throttle Position Sensor signal DBW

Hi..

I'm trying to guess where to find the TPS wire on a DBW S2000 (MY08)

The sensor is not located where the non-DBW sensor is located.. but I assume that somehow the TPS information is needed and that the signal should be available somewhere

What I need is a 0..5V signal (5V full open and 0 full closed for example)

I need to it to tap it into a Innovate LMA-3 Interface.

Any help would be appreciated. I have tried to used the search but I did not find a direct answer to it.

Thanks!

I have "found" this sensor



it's not really a TPS but a "accelerator pedal position sensor", so I suppose that this sensor is used by the ECU to decide how much to open or to close the throttle body..

The TB itself must have somewhere a wire that indicates how much the TB should be opened or closed.. (that's what I am searching)

But I don't have any DBW TB wiring diagram (or the accelerator pedal sensor).. does someone have it? (Helm's manual maybe?)

get a voltmeter and check the voltage signal while someone presses on the gas pedal. Check every pin ...

Thats a start.
