Loaded question for me. I also have a 12 Ram with the OEM TBC. I tow 8500lbs, 5'er has 12" brakes and the 5'er is brand new. My OEM TBC is junk. Our last TT we had the TBC barely worked. Original was replaced under warranty @1,000 miles. New one is not much better. Traded the TT in on a 2013 Fox Mountain 5'er and now the TBC is over reacting to all conditions. There are several settings to choose from. I have my set to elec light and use 5.5 on gain. However when in town I have to turn it to 0 gain. When stopping and starting or reversing it's like a shoving match between the truck and trailer. Jerking and what not. When I come to a stop and let up on the brakes to go the 5'er brakes take another second to release. Making a jerking motion in the truck. Reversing is horrible, I just get out and unplug the 5'ers 7 pin plug. Even when setting the gain to 0 in town and backing up you can still feel the truck and 5'er not working together. There has been numerous reports of bad TBC's with the Ram.
Sorry to get off topic on this, but hope yours works better than mine does.
To set it you need to do the TBC road test, drive at 25 mph and slide the manual brake lever over and if the brakes lock then dial back the gain till they don't lock. You want the TBC gain set at the point just below where the trailer brakes lock up. I would just start at 7 and work down. And like everyone says all trailers are different so gain will be different.
Another confusing thing with the Ram's TBC is there are no guidelines for weight settings between light and heavy. I do know that with my 8500lb 5'er that the heavy setting is too much.
