Hello,
Have a problem wiring my DBW module, actually DBW is not a problem to connect, problem is in accelerator pedal signal to ECU , as i understand i should connect signal wire from accelerator pedal to ECU TPS in pin. But i have two signal wires from accelerator pedal. So how could i do now ? In attachment i added diagram of ecu and accelerator pedal connection and pin descriptions.

I used D8 as TPS in and D7 as sensor ground for pedal position sensor, When i turn ignition on there comes whistle sound from throttle body is that ok ? Also i have VDO 408238424001 throttle body, when i choose it and sellect all inputs in software, when i turn ignirion off and turn it on again, all settings stay the same but throttle body wizard is changing my VDO to BMW 40823842500.

Looks like its normal. The frequency of this sound should be same like frequency o changing polarity of the electromotor. So you are basicly very fast opening and closing the plate... And this make s this sound... i think.
