Yes - some of them were very impressive. And much neater...I was confident with the electrical/electronics side, as that's what my background is in, but physically getting it all set up was fun.

On a similar note - I finally got rid of my alternator whine yesterday. Went round wiggling everything until it vanished then tightened everything and fixed my cable runs. Not sure what the cause was, but 'magic' fixed it

Also managed to arrange things so my hands-free phone kit should fit - a fun job as there isn't a lot of room behind the dash!
