After 63K miles I looked around and decided to change up my interior a little. Thanks to climkt for his inspiration http://www.e90post.com/forums/showth...ted+shift+knob
and Tischer for their awesome OEM prices and A+ services. I got the Z4M illuminated shift knob fitted on my e90.
I would like to share my experience and create a DIY for it. If you choose to follow this DIY, you agreed that I will not be held responsible/liable for any problems when you attempt your own DIY using this DIY. I am no mechanic nor an electrician nor should I be held liable for typo errors either, so do this at your own risk.
Tools/items you will need:

Tap-In squeeze connector for wire from RadioShack (64-3053)
