So i'm going to be getting my Pioneer AVH-P4100DVD installed as soon as i get the last parts i need. I was searching through the FAQ but couldn't find the info i needed.

I'm looking for the GM-OS harness for my 09 SS/TC with ONSTAR, and the steering wheel controls that go with it. Where's the best place to buy?? Also what are the part numbers for said pieces.

Thanks guys!

 

Ebay,
Axxess Gmos Lan 04 is the harness you want

Audiosavings is a great ebay store, I ordered a Line Driver off them for an install I was doing, it was at my door 2 days later, plus $99 is a decent price

PAC is the company that makes the interface for the steering wheel controls
