that's part of what they call the footwell module in these cars and I think it's used for programming- it has nothing to do with the phone installation, at least it didn't for me. If you have the wiring up in there, then the antenna wiring should be tucked way up in there somewhere and you just have to find it. As for the mic wiring on the passenger side- it really was quite a pain to get back up in there- I went through the side kick panel under the glove box on the side under the A pillar, and then through the glove box, it was a lot of wiggling and suffering and just concentrating, but I didn't remove any pieces that said airbag on them or that had to do with the airbags
