2018 Jayco Greyhawk 29MV power for towed vehicle battery

[Smk52]

Does anyone know if there is 12 volt power to the connector on the back to charge a towed vehicles battery and if so which pins?
Thanks in advance.

You can find out for yourself with a multimeter. At 7:30 and 4:30 on a clock face with the orientation lug in the up position, are the Ground and Brake power. At 9 and 3 are the left and right turn signal and brakes. At 10:30 and 1:30 are the tail lights and Aux. Whether they are on the left or right depends on if you are looking at the pins or the plug. That is why I didn't use left and right. And the center pin is for backup lights.
