C6 aftermarket radio wiring HELP
Okay I've tried looking and searching and cannot figure out what to do. I have an 07 with base radio non Bose and non-nav. No onstar as far as I know. Ordered a pioneer radio from crutch field and they sent a Gmos-04 wiring harness. My confusion is do I need the black box which I assume is for onstar equipment? I have the extra relay and understand that wiring.
The large gray plug will connect to c6 radio harness. The top black plug goes to the black box with radio harness (onstar). I have no clue where the small gray and small black plug connect. Are they not used for my application? And the 3.5 mm audio plug, no idea where it goes.
Thanks in advance. Radios have changed since I was younger.

After a beer I have a little more concentration. The small 12 pin is for steering wheel controls so I won't use. Still not sure where the 12 pin gray plug goes. I have the rest figured out. After reading further, it appears you still wire thru the black box with or without onstar.

You do need to use the box.
Connect speaker output wires from new HU to same color wires of gmos. Same with black, yellow, red wires.
You don't have to wire in the relay if you bypass the box and connect HU blue/white "amp remote" wire directly to wire at pin B3 of the 24 pin harness that connects to the car (relay is there because gmos can't always handle the current draw that the stock amp requires on the trigger wire, the new HU can handle it just fine, so bypass the box and relay isn't needed).
Orange wire in gmos is useless, for dimmer wire you need to tap the gray/black wire under the TC/AH button.
If you have rear view camera you can find reverse signal in footwell, see post #2 HERE
Other plugs aren't needed in your car.
