*I found no switched live - the green/orange wire was dead with and without the ignition switched to acc - I took the live from the cigarette lighter and it works fine
I also spent a great deal of time with the speaker wiring - it looks straightforward on paper but the reality can be confusing
I found that using a multi-meter helped
Also, checking the Haynes workshop manual revealed how much the wiring can differ between years and models
Be careful because the fuse for the live also protects the boot unlock button and it's located in the boot - see my posting on the forum under "Bodywork" for a solution to that
