I want to wire my Terk XM commander into the G with the Pac AAI-NIS adapter but I need the wiring scheme so I can wire it to go on when the radio goes on. I need the 12V Constant, Accessory, and Ground. I am assuming they will be Yellow, Red, and Black, are they? Thanks

 

No, they won't be. If it were me I would go under the drivers dashboard and grab 12VDC there along with an ignition source. You can grab a ground under there too. The wire colors will vary based on the year of car and if its a coupe/sedan. Find the harness that goes up to the key cylinder and all your wires will be there.
