I'll keep an eye on your update. If you can, take pics of yours too so we all can compare. You can't shit about this when you google search it with good details.
I searched and searched for this thing tons of time no matter what I put in it gave me nothing. I feel your pain. I will post of pictures of what I did and I will make a how to for this thread also if I find the time so hopefully it will help other people out.
However touching on the 3 Harness you refer to. We have 1 for the Climate Controls. 1 for the Antenna and 1 for the Radio. The Wires I said on the ones I connected to harness refer to the car harness that plugs into the Metra Adapter for the Stero. The Wires that I say (Harness) are wires that are featured on stock car harness. I T-Tapped into.
Also with the Grounds that the Wires have to get grounded to. I took the Grounds for the Metra Black Wire and the Blue with Black and Gray and T-Taped them and combined them and then t-tappad them into the ground on the 12 V Plug in the Console Box so I can ensure I was getting a good ground!
Okay, I found a link to the vehicle application guide for the axxess. have you guys looked at this yet?
I remember this being a little hard to find because its not just there to click on. This will be the solution for both of you. Just put in your model and it tells you exactly which colors. This is the guide I used to install mine.

Also in reference to that. The Manual they gave me didnt work.I connected what they said in the booklet that they provied with the Axxess and it didnt work. If you look closely the Pins they refer to do not line up with the corresponding wire that they say. Its hard to explain but I am going to try your way first and see how it comes out, then I am going to try my way and take pic of both and see which one works and try and make a write up on it.
They just say what Pin the wire is not the actual color of the wire and people seem to hook them up backwards or fail to find the right pin. It would save people alot of trouble if they just said what color wire on the stock harness then the PIN they want you to connect them too
