I have no idea which is correct but don't really think I want my trailer brakes to fully and instantly engage unless the trailer is completely disconnected and off on a solo trip. If the E-brake engaged while the chains are still intact I could see that causing both the tow vehicle and the trailer to be involved in the subsequent crash. I'd like to leave the tow vehicle out of the crash if possible so my E-brake will remain connected so that it pulls only if the hitch and chains both fail.

Great points. Never thought about two scenarios. It would be smart to verify the 7-pin is not bound up too, causing it to unplug if the tongue came off. I've seen a bunch of zip tied and wired loops of some thinking they are preventing issues, when they may have just caused the 7-pin to pull out if the tongue is off and the chains reach their limits in length.
