I got it from Best Buy and installed with the instructions
Yes, I got Metra Axxess GMOS-04 wiring harness for monsoon
and the Metra Axxess ASWC for steering wheel controls.
It was pretty much like any other deck install in the end, match the factory wires with the aftermarket harness.
The ASWC requires you to connect the following:
Black - ground
Red - 12v power
Green/Orange- splice into the actual blue wire (A6) from the factory harness.
and then the trick... the Purple wire right next to the Blue one on the factory harness, you have to run a jumper to the 12v power cable as well.
