Vauxhall wiring diagrams - Viv
I am desperately searching for a wiring diagram for a Vauxhall Omega - does anyone have, or know where I can get one? The Haynes isn't quite as in depth as is needed!
It's a T Reg (not sure what year that makes it!!)

>>The Haynes isn't quite as in depth as is needed!

In what way? the diagrams in the back of my Omega Haynes manual seem to show every wire, so what do you actually want to know?

Vauxhall themselves didn't do wiring diagrams on their TIS CD until 2000 for the new shape Omegas, however they can still be useful for the later older shapes like yours, especially for stuff which didn't change between old and new shape.
You can get TIS & EPC (Technical Information System & Electronic Parts Catalogue) on ebay. Get the latest version you can, (last few years). Search for "vauxhall tis"
What is the problem you are having?

Ashok; where are the wiring diagrams on the TIS disks? I was poking around on my TIS2000 disks last night and couldn't work out where the Omega ( or any other) wiring diagrams where.

I have not found full diagrams on the TIS2000 system but I have occasionally found parts of the schematics. Not easy to find at the best of time in my experience so I stick to the Haynes manuals.

Fair enough Deryck, not just me then.

I notice from the Haynes manual for my wife's Zafira that they have changed from the proper ISO/DIN standard wiring diagrams used in the Omega manual to a mickey mouse style that looks more like a powerpoint presenation. i hope I don't have to rely on thes efor any serious electrical troubleshooting :-/
