hey guys,
I'm going to be installing my s-afc this weekend. i have installed a few of these already. my question is what wire do i connect the (grey) throttle wire to? the pressure sensor in the engine bay? if so which wire? or is there a pressure sensor that goes to the ecu? thanks, i've tried looking for hours.
if any one has a pic that would be great.

Read the FSM. It has the pinouts for the ECU. One of them is an input that has the pressure sensor. I don't know what pin it is for the turbos, but you could look it up easily enough.

... I could, but I don't want to make your life *that* easy. You should know your way about the FSM if you're doing engine electronics work.

Just hook it up to the brown/red wire on the pressure sensor.

I think you want to run a wire to your engine bay....and connect it to your harness before the fcd....(dont wanna tap from ecu)

forgot to mention....the colour is brown/red wire on your pressure sensor harness...

not sure if brown/red wire from pressure sensor is the same between s4 and s5...

Good luck!!
