no, I did not get an answer to my question.
What I ended up doing is I bought a FM Transmitter. The one I bought is not advertised on radioshack.com any more but this is one close to it.

and I had a adapter to connect the wire from the cd deck to the transmitter.

The antenna wire is in the left rear quarter panel and it plugs into a amp in the that quarter panel then it's turned into a wiring harness to the front. Crutchfield.com Has some of the adaptors and a the new face plate if you want to change the radio too.
