If that wire goes to where the blue wire in the Bargman cable connection at the fridge, so be it. If it goes directly back to the brake wiring, that's good too.
The way to test it is to lift one wheel off the ground, pull the pin out of the switch and that wheel should lock up. Put the pin back in and the wheel should be able to turn. Be sure to test both sides.

@Wavery Absolutely great advice as always. knew it didn't seem right when I looked at it. Will def. run the test next time. Oddly enough when I pull the wheel I can hear the breaks are engaged but if it's wired to the Tow vehicle in the event it separates than it will not have power to engage the breaks.
