Hello everyone I need a little help. I have a 03 g35 sedan. My Problem is that i have the metra 99-7604 that came with the car and an aftermarket radio but i dont have the connecter for the A/C controls. So my question is can i hard wire the metra 99-7604 to the car? I called metra they wont sell just the cable so im kinda stuck. Can anyone help or point me in some sort of direction?
