[ forum won't let me post links to pics yet, so I had to work around that ]
A few months ago we purchased my wife a 2012 Acadia.
We replaced a 2005 Terraza. The Buick was loved, but it
didn't look as cool as the Acadia.
One thing I miss was the homelink buttons on the overhead console.
I read through a lot of posts and decided to try the "simple" swap.
I bought an overhead console from a 2009 Traverse. The ad said
it will fit the 2007 to 2015 Acadia... great! $40 plus shipping.
I received just what I ordered... correct color, buttons, etc.
I removed the overhead console from the Acadia and discovered
that my 2012 console has a gray 12-pin electrical connector:

The one from the 2009 Traverse has a green 16-pin connector.

I managed to remove all the wires from both connectors without
I discovered that the 2009, green connector had eight wires, and the
2012, gray connector had only six.. this could be interesting.
I got the bright idea of looking at the connector in the ceiling of the Acadia:

It has eight wires... This may actually work!
When I started pushing wires from the 2009 console into the
2012 connector [using the photos as a guide], I discovered
- The 2009 console has a red wire that the 2012 doesn't, but the Acadia has a red wire that wasn't hooked to the console
- The 2009 console has an extra gray wire, but the Acadia has an extra gray wire that wasn't hooked up
- The 2012 console has a green wire; the 2009 console has an extra black wire
I traced the "new" red wire on the 2009 console. It runs to the homelink.
I plumbed that to the connect to the red wire in the ceiling of the Acadia.
The extra gray wire in the 2009 console runs to the homelink. I plumbed
that to the "extra" gray wire in the ceiling of the Acadia
I fired-up the ohm meter and discovered that the green/gray pair in one corner
of the 2012 go to the OnStar/bluetooth mic. The black/gray pair in one corner
of the 2009 console go to the OnStar/bluetooth mic in that console.
I plumbed-in the black/gray the same as the green/gray was.
I ran out of 2009 wires at the same time I ran out of wire in the
ceiling of the Acadia. I put everything together and it works!
A quick trip up the ladder to push the "learn" button on the garage door
opener, and we're back in business!
No more fumbling in the console for that opener button.
Now, I need to track-down the cup holders that go in the back
of the center console :-)
I'm sure others have done this same thing, but I haven't seen any pics
like the ones I took. I hope they can help someone.
