Fellas, i was thinking about making a simple (cheap) 10 LED display to indicate the turbo pressure of the C5.
Of course, this could be retrofitted to any TD/HDI with a 5V MAP sensor.
Now, which wire does what? Mine has 3 wires, but i couldn't find anything about that aspect on the net, nor am i willing to spend some euros if i blow mine up
I would post the schematic here, of course

!
Cheers!
