Can anyone help me out with wiring diagram / pin-out for the vacum electrovalve for the 1.6 HDi? Part 1618C9.

Which of the pins are what?

I guess one is +5v or +12v, and the other one is (-) trigger PWM singal controlled by ECU.

Trying to use one of these to control the turbo on my 405 T16 project :)

If anyone got access to wiring diagrams in Servicebox, it would be greatly appreciated.

As far as i can tell it would not matter as its just a field coil and the valve moves in relation to the power applied basically 1 side is 12 volts and the other is earthed through the ecu this varies from zero to 100 % earthed depending on requirements

Aha ok, so it'll not hurt the valve if I put constant current on it either, to check which of the air-ports that'll be correct to use for a given wiring setup?
