Good morning everyone. So I got a 2019 ram 1500 Laramie (does not have the ITBM). Trying to tow my Forest River Surveyor. The trailer have a 7 pin connector. So when I connect the trailer to the truck, the trailer brakes are engaged. I can’t pull it of course. How do we disengage the trailer break. Please advise or a link of how to. Thank you
