  1. i installed subwoofers and a amplifier to my factory bose 6 disc cd changer and when i went to plug the wiring harness into the back of the radio, my radio works fine but my cd player doesnt work and wont even let me eject any cds or load them. if you have a solution to this problem i would highly appreciate it.

  2. I have a 2005 Tahoe and I can’t seem to find the steering wheel controls plug. I am trying to install a PAC steering wheel control for aftermarket radio. If you can tell me where the plug is located that would help tremendously.
