Is your Fusion radio wired wrong?

Getting ready to convert from the BIM to the ACR. I will install the switch right there under the jump seat next to the fuse panel. Since I am not running wires to the dash there are some changes to Wachuko's wiring instructions.

I have laid everything out and studied Wachuko's list while looking at the schematic. I want to measure twice and cut once so I am pausing to double check my approach. Can anyone let me know if I am making any mistakes with this wiring approach:

1. BIM Gen Set (gray) wire to green ACR with added 2 amp fuse
2. BIM Ignition (white) to brown ACR
3. BIM Dash wire (gray) abandoned - no connection
4. BIM Ground (white) to black ACR AND switch #1 (is that an OK approach or should I pull ground from somewhere else?)
5. Orange ACR abandoned - no connection
6. Yellow ACR to switch #7
7. Red ACR to switch #2
8. switch #3 jumped to switch #8
9. switch #8 to ACR coach terminal A using 3/8" ring connector with added 2 amp fuse.
10. Just confirming that both cables on the BIM coach battery terminal are moved to terminal A on the ACR. One is only 6" long so probably need to replace it given the new ACR terminal location below.

Also, I recall reading someone's post on the logistics of getting the ACR into the area where the smaller BIM is located. Not to mention the coach and chassis terminals are reversed and the short stubby cable on the coach terminal is not long enough to move. Did others move the large Magnum forward closer to the bathroom bulkhead and install the ACR sideways with terminals pointing towards the driver seat? Or did you move the ground terminal and battery switch further outboard and install the ACR with terminals pointing inboard?

Thanks for all your coaching and guidance.

The ACR is symetric. It doesn't matter a bit which of the heavy battery cables go on which post. It works exactly the same either way.

In my 2014.5, everything is in a box under the couch and there was plenty of room for everything. Worst thing is that whole area looked like a bowl of spaghetti due to the sloppiness of Airstream wiring. I miss the days when I was prototyping hardware with IBM where all the cables were beautifully laced and labeled.
