No, you are supposed to have the lengths of the wires and cords so that the 7-pin gets pulled out before the breakaway pin does. With a TT instead of a 5er, you also have those safety chains. If the TT comes off the ball to the chains, I am not clear if that counts as a breakaway. I think I would like the 7-pin to still do the braking then and not get pulled till the chains broke too.
You can of course believe anything you want, but I do not share your concept of how the breakaway switch and the 7 pin connector work together. I think you will find your opinion also not shared by those that have studied this issue in some depth and I wish you good luck in trying to control a trailer and not running into a ditch while trying to control that trailer with one hand while fiddling with your brake controller that has "disconnected from the ball" and is only connected by the safety chains with your regular brake controller.
I want my brake away switch to activate just after the tongue becomes unconnected from the tow vehicle, but is still attached via the safety chains. I could care less what the status of the 7 pin plug is and I will have "BOTH HANDS" firmly planted on my steering wheel attempting to control my TV as best I can until my speed is reduced to a safe level or stopped.
