Need Help Badly!!!!!

Thanks for the replies everyone! Decided to give it a rest until today. Better that than get a bit heated and break something.

How does the harness unhook from that clip thing? I can't see it and am mostly going off feel so I don't really know if there is a trick to it or you just prise the thing off as best you can.

Thanks for the tip on the bulb thing two. I'll watch that.

Cheers
