I just opened my GMOS 04 (which I believe is the only adapter I need except for the antenna to connect the Z2 to My Hummer H3 with standard radio and Onstar) I looked at the directions for the GMOS and step 2 says to connect the red wire on the GMOS 24 pin connector to the radios Ignition wire, Problem is there is no red wire coming from the GMOS, All the other wires are there just not the red one. Do I need this wire, I went to Circuit City and looked at anouther GMOS 04 and it also did not have the red wire. Here is Link to the directions for this setp, It's on page 3 step 2.
