I probably have 50 or so head unit/car stereo installs under my belt, but this is my first having to use a GMOS-01. I have an 05 TBLT with ONstar and no Bose. I am wiring up the harness that I bought and there is no switched 12V wire (the red wire). Am I missing something or did I get a bad harness?
The box had been opened and I am not impressed with the quality of the harness and I didn't get any instructions with it. I guess that is the risk of buying from an ebay seller. Any insight would be appreciated.

It should come with the red 12v wire. I would have to say you got ripped off.
