The most difficult part on the jb4 for me was getting that damn power wire out of the green box. I couldnt believe how much trouble that little ba*yard gave me! Plumbing the USB through the dash was a small challenge as well but once you do it you're golden. Nice to know how things are sorted in the car too.
