Thanks. If there is any info on voltages, I would love that too.

It doesn't come unlocked easily. I basically pried up on the two spots that look like you can get a screw driver under. Use a fine flat blade and pry. It's not as obvious that it's unlocked as the other connectors.

I got it thanks!

But now my white wire pin 43 broke.

Not sure if the same pin can be recycled.

Repaired it and my unit powers on!

I have everything taken apart and ready to do the wiring...and I can't find my CD!

Can anyone tell me for the 3 wires that run from the glove box connector to the radio connector, which pins the additional 3 wires get plugged into?

The Onstar X2 connector?

Pin 5: Silver Shielded
Pin 6: Red Wire
Pin 12: Black Wire

Thanks man!
And that goes to where on the other connector?

Those leads should be the longer wire from the Mylink Harness. It's end is already connected on the headunit side connector. On the glove box onstar side you need to pull out the x2 connector (12 pin smaller or the two) from the onstar box. You'll have to unlock the x2 connector which is tricky as you have to pop the small white plastic piece up.

Then stick each of the wire pins in the places I listed and then close the x2 locking connector.

Not sure I follow. I got the longer strand of the gray harness (red, black, and silver) tapped into the X2. Now have the shorter strand (red, black, and silver). Which pins on the A20??

[Pagliaro]

Sorry it was I who wasn't following you.

The shorter go to the faceflate harness a20 in the following slots:

Pin 5: Red Wire
Pin 6: Factory Black
Pin 7: Taped Black
Pin 14: Green
Pin 18: White

On a side note I feel like a dumb ass I drained my car battery somehow as it won't turn over. Ugh.
Service messages galore!

Hopefully I can get it running.

So everything seems to be working. But...the green wire came out of the pin that goes into A20 but doesn't seem to effect anything. Does anyone know what the green wire does?

I've noticed a few of us have stated no trimming needed for the console bezel.

2011 : Storage tray bezel fit perfect for me without trimming.
