You can get at the wires easier if you pull the panel thats behind the hood release. Thats what I did, The wires have enough slack that you can pull the ones you need out of the bunch just a bit.

I just tapped at the spot with long speaker wire though, I ran that wire to the trunk and mounted the LOC in the trunk where the spare ground is on the right side behind the carpet.
