I have read all (I think) the posts on pre-wires, and am confused as to where to look for the wiring harness on an '03 Sedan...Is it below the rear package shelf to the right of the woofer, or near the spare tire area? I don't think I am pre-wired, but would like to know for sure...I see some posts say to look in the tire well and remove a brass nut...which I don't have and other posts showing the package shelf...
I have an early model (Nov, '02) so it wasn't automatically pre-wired. I have the SAT button on the audio console,the Bose system and Navigation.
Thanks!
