4ES GTA Car Kit (Bluetooth Addon)

Ordered this to get bluetooth working. It's great and sounds amazing. I did have an issue initially that I thought I would share.
Apparently there are several different stereos that go in the ES. I got the kit and was excited to try it out, but the plug on the harness they sent did not exist on my head unit!

Apparently, this is what it was expected to look like:

I contacted GTA and they asked if the second plug on the back of my stereo was being used so they could determine what adapter they needed to send me. I think the other socket is for steering wheel controls which my car does not have (unfortunately).
Within a few days they sent me an adapter that went from their harness to the other socket on my stereo and it works great.
So if anyone is thinking about installing one of these things, check the back of your head unit to see if that 3rd plug exists first, and ask for the adapter if it doesn't.
