Second, I have yet to see a configuration that would allow the breakaway cable to be pulled when the coupler separates from the ball but the chains are still attached. It would require some very specific-length cables and attachment points such that the cable is pulled if the ball drops more than a couple of inches, and that assembly would still need to be able to articulate as the rig makes turns and traverses hills and valleys. That setup only exist in theory as best I can tell...
You are correct that your cable lengths need to be closely set and I have mine where when the safety chains are fully extended the breakaway switch is pulled, but the 7 pin cable hopefully will still be connected. I have tested my configuration by attaching all the cables/chains with the tongue off the ball and at the same height as it would be normally and then slowly pulling the TV forward till the chains are taught. Here is a picture of what my "ACTUAL CABLES/CHAINS
" looks like and this is not a theory, but real and I'm sorry if you still don't believe it's possible, but I know along with a lot of other folks in past posts say it is ;):
