Hi
I am connecting up a vdo unit with the no. 410.209/009/001
Alpina no.62 10 026
I know what the green and brown wire does but cannot work out what the grey wire is for.
Any help on this

Thanks

The pin-outs for the VDO unit was posted here:

Let me know if you need help with translation.

BTW I have question about this unit: is it reading the pressure or only the vaccum? My german is not enough good for that article on e30.de (as far as I can read german it is saying that it is reading +- 6 bar but can anyone confirm it?).
Cheers,
Jan

The pressure shown is manifold pressure. For a non-turbo car that will be between 0-1 bar, for a turbo car obviously more.

According to the text on e30.de it does.
