Octy MK1 Stereo ISO cable colours...?

[SilverBandit]

so, some scrotes nicked my Blaupunkt stereo the other night :irked: and yes I know I should have taken the removable face in the house. However... they CUT the damn power ISO connector (Block C) off. So now I'm trying to re-fit the original Symphony HU and I can't find anywhere that tells me what colour cables should go to each of the pins in the ISO block for power etc. (the Haynes manual doesn't mention these left-over cables either.)

Please could someone check the following and identify the left-overs?

1 ?

2 ?

3 ?

4 Red/White - +12v Perm

5 (empty)

6 Grey/Blue - Dash Illumination

7 Yellow/Red - +12v Ignition

8 Brown - -12v Earth

I have the following cables left:

a thick red/white... (looks like another +12v)

a thin blue/white...

a thin grey/white...

I don't actually care what they do, I just need to know which colour goes to which pin...

Thanks for any assistance.
