Wiring diagram for C5 Mk II

[martinwiseman2000]

Hi,

I guess the wiring diagrams in the Haynes manual must be for the Mk I as they have little resemblance to the actual wiring of my vehicle (C5 Hdi VTR, 57 reg).

Are there any wiring diagrams available for this vehicle, either free or paid for?

If not, can anyone help with my specific query. I want to add an active subwoofer under the passenger seat for which I need an unswitched supply rated for 10A plus a low current switched supply. Any suggestions as to where I can safely take these from?

Thanks,
Martin.
