I got my Mini this Saturday just gone (It's a Rover Mini Cooper, 1275 with HiF44, 1992) and I love it to bits already!!
Problem is that it came with a Mini branded CD player that needed a code, I've got the code but whenever it turns on it just says 'Code Wait'. But that's a different story. So anyway because I couldn't use that CD/Radio player I thought I'd just use my brothers old one so wired it in. I wired it in wrong... (Please be aware that I am currently doing an electronic engineering apprenticeship course and should have known better than to just plug something in which makes all this a LOT more frustrating to me) and as I was leaving my friends house his dad noticed my rear lights were out, so we started fiddling around for hours and hours and bla bla, but it ended up with smoke pouring out of my mini (which at the time I had owned for about 6 hours) and some wires therefore exposed. Now the first thing is that I don't think the CD player should have even been on the circuit for the front side lights, rear lights and dash lights?? and the second thing is, will the whole loom have to be replaced (guessing that's the more expensive option) or can the messed up wiring just be replaced (cheaper excellent amazing option)??
Just to let you know - We got it working in the sense that all the lights come on when I switch them on but the hazards and interior lights don't work (but I think that's a different circuit anyway?) and If you turn the sidelights on you just get dim head lights... but I can drive it (Y)

Sorry this went on a bit but any advise would be great!
Thanks, Alex
