Silly question, but I've failed so far to find an answer.. Where do I find the switched (i.e. switches on and off with the ignition) 12v feed. The harness adapter I got from Crutchfield only provides a permanent 12v feed, with no instructions on where to get the 'accessory' feed from. The old stereo switched on and off with the key so there must be a switched feed in there somewhere!

Installing a Blaupunkt San Antonio 640, btw.

Thanks,

Neil.
