I need to pick up a live 12v supply under the bonnet when the ignition is on. I have looked very carefully and there seems no suitable cable that I can piggyback. The maximum current I am likely to draw is about 500mA. The fusebox is an absolute nightmare and is so packed with cables that its impossible to see what cable goes to which fuse.
The Roadster is a 2009, series 2.
Any ideas would be appreciated.
