06 non amplified stereo

I think for all of you 00-05 MC rollers use the same t-harness right. but how about mine, like the subject says no amp,, crutchfield.com says they dont have the harness for the 06. I had an 03 grand am and had to have a t harness and the stock radio stayed hooked up in the trunk. So which harness do I need. By the way I don't care about retaining the chime... Thanks in advance

Does your car have Onstar?

Well it appears that it does not matter if there is onstar or not.....
 
You need the same harnes I have    GM-OS-LAN-O1
