I have a 2007 750Li w/ Comfort Access.

Thanks in Advance!
You would need a socket first like this:

and then some an Add-a-fuse that looks like this:

You can find the add a fuse at autozone, pepboys, etc. Just make sure you get the right size!

As far as what fuse to tap into, I'm not really that sure but there are a number of possible fuses. For example there is the coolbox/refrigerator fuse that's probably unused in your car. You will need to put a the add a fuse in there, HOWEVER only plug in the fuse for the wire sticking out, do not plug in both!

Then simply run a power wire to the power side of the outlet, and run the negative/black side to a grounding point.
