Hey guys, first time user with this forum so bear with me... I'm trying to install an aftermarket stereo in my '05 Z. I received the harness adapters from metra, but they only seem to believe that the Z takes two harnesses... but I got the Z with four harnesses that attach to the back of the factory stereo. Could anybody help me figure out the purpose of each harness and perhaps provide me with a link to harness adapters that would work?

If you need any clarification, please let me know. Thanks in advance for the help, guys!

 

Bose system stock?

 

the other two harnesses are for the nav unit hook up and stering wheel controls. they do not make any harnesses that connect to these plugs. really their not needed unless you want to keep your steering wheel controls.
