This is what I did to my coach which is a 2020 hurricane 29m. Your coach may or may not work the same so dont blame me if something doesn't work.
The axxera avm211nav that came with my coach was installed using a custom pigtail. This decision by thor made it difficult to replace. This is the harness I created to connect the non-standard thor harness to the standard eonon harness. You need a 12 pin molex connector and a set of male universal iso connectors.

If you look at the second photo pins 1, 8 and 9 are in the shape of a D. The pin out is as follows:
1 - black
2 - yellow
3 - red
4 - empty
5 - grey
6 - white
7 - purple
8 - green
9 - grey black
10 - white black
11 - purple black
12 - green black
Orange and blue are not used from the iso plug.
From the eonon pigtail, you need to attach the orange which is reverse camera control and the brown which is the brake sense wires. I wanted to be able to reverse the install if I didn't like the eonon so I attached a spade connector to each wire.
In the coach they used butt connectors for these two wires. I attached male spade connectors. The brown eonon wire goes to the green brown thor wire and the orange eonon wire goes to the purple thor wire.
Thats all there really is to it. Reconnect the rearview camera, the GPS, the USB and the antenna. Lastly install the trim and you are done.
