Ready to fit the following 'hotfix' to solve my warm starting problems (I hope).

I am following these instructions:

http://www.tawpark4x4.com/instructions/omega_hotfix.htm

I am pretty sure I have found the blue/grey wire in the loom (thinner than I expected though).

Also found the red/white to a nearby relay.

Little puzzled as to the bunch of black earth cables. I am thinking that these may actually be brown on my pre-facelift Omega.

Can anyone confirm please?

Cheers!

My experience of Vx. wiring looms is solid brown wires are, as you say, earths.
Blacks are usually live...

Thanks!

I'm not going mad then 

Will test for earth on the brown tomorrow.

Cheers!

Yep! That was it! - Thanks!

Brown is definately the colour for earth (and not black) in an Omega. Maybe they should include that in their fitting instructions for the Omega version 

Having fitted the unit according to the instructions, there is no obvious sign of it doing anything at all. There is a red LED on the circuit board which does not illuminate with the ignition switched on so maybe the scotch lock connections are not good enough. If I take the clip off each and then test each metal bar with a voltmeter, there is 13v with the ignition switched on and zero without so I know I attached it to a 'switched' power supply. I cannot detect any current at the other end of the scotch locked cables so one or both of these may not be sound.

Will soldier-on tomorrow now :-)

Cheers!
