Is the pin on your 7-way dirty or corroded? That's usually what causes intermittent brake output signal on a vehicle 7-way.

You can also try probing the brake output circuit with a # PTW2993 to see if the voltage is on the wire but just not making it back to the pins of the connector on the 7-way.
