No need to remove. Just tuck the wire under the leading edge of the headliner. I used a putty knife to distend the headliner enough to push the wire in place as I ran it along to top to the "A" pillar. Tuck the wire under the edge of the "A" pillar and run it to where the it ends at the top by the door closure. Run it under the gasketing dowin to the fuse box area. There you can slip it behind the side of the dash and come up into the fuse box area. Lots of room there. The screw that holds the fuse block to the metal dash pan easily accepts a "U" type crimp connector for the ground. Just loosen and slip it under.
For the positive power connection I've alway used a mini-fuse block add-on. Slick little device that you pull an ignition fuse and put this little device in its place. It provides a place for the original circuit fuse and a place for an additional fuse that is wired to a pigtail hot lead, pre crimped with a female bullet connector. It's a heck of a lot cleaner than using a T-Tap or stuffing a wire end under an existing fuse.
You can pick up the Mini-Fuse Add On at Auto-Zone and Pep-Boys. About $4.00
