Was going to add an add'l jack to the music jack on the panel and mount it on the inside of the glove box..
Looked to be a hassle to tap into those wires and will probably never use the jack on the front, so I just moved the existing panel jack to the inside of the glove box and plugged in a 12" jumper. Will just leave the 1/4" hole in the panel... looks OK. Can lay a CD or MP3 player inside the box to jack in music.
