With a little time today I decided to properly run the Wilson 1000 antenna. Prior to this, it basically came through the door jam and just ran through the interior. I wanted to clean it up and keep it hidden. Here is what I did:
1. Remove the rear cover in the rear
2. Remove cover by front passenger
3. Pop loose B pillar cover. Note that there is a little plastic piece at the bottom and you have to snap out first.
4. Remove kick panel cover on passenger side (where the ECU is). You push in on a little insert, then slide the clip out. Now you can pivot the cover out of its place. Make sure the floormat is out of the way.
5. Now you can run the antenna wire between the panels. What I don's show here is that I pulled the weather stripping out of the way. In addition, when putting the weather stripping back on, I cut out a notch (not on the rubber itself, but the back support) in order to allow the weather stripping to go over the wire and sit back on.
6. Here you see the wire in the corner. I had to loosen the two screws to the grab handle in order to properly push the antenna wire all the way in.
7. The B pillar at the top is still secured since I did not remove it. The wire easily went behind it.
It is the bottom half I popped out. The picture displays the wire before being dropped in completely.
Here is the wire again before being tucked in.
8. At this point I ran the wire underneath the factory clips for the factory harness.
9. I pulled the carpeting by the passenger footwell back and completed the run.
10. This is the only part I don't have a solution for. But this is pre-weather stripping reinstall (at which point I placed the notch).
11. Finally the completed picture. You can see a slight depression where the weather stripping went back on but I think it is pretty good.
I haven't tested it yet. The worse that can happen is the antenna wire picks up interference from the factory wires, but given the shielding I doubt it will happen.
On a side note, I wasn't trying to take great pictures here...so forgive the lighting.
