FYI fuse 108 is the one. Used it today when fitting an autodimming mirror from a mk3 mondeo . switches on when ingnition is on.
Fuse 100 (At least on my Focus) also switches with the ignition. It's the fuse for the electrics (Heater head switches and illumination, heated windscreen/rear window switches/illumination, rain sensor (if fitted), sunroof (if fitted) - looking at the wiring diagrams for the Mk2.5). Used a fuse tap on that today to mod my lighter socket to switch with the ignition.
Made the video un-private... does help doesn't it!
I've got a good few more clips of, lets just say, poor standards of driving. I just don't have the time to put them online! It's really useful from my point of view though, if anything happens I can go back and watch it again!
