The continuity check would tell you if the brake output wire is connected all the way back to the 7-Way trailer connector on your 2008 Dodge Ram. It is possible that it terminates in a forward connector near the drivers side front wheel well.

It could also be that the brake controller is not sensing the brake magnets. If the trailer connector is not pinned out the same to be a mirror image of the vehicle side that could be the problem. If the trailer has a breakaway system then it could be the wiring for it needs to be examined and repaired.

A dirty or corroded trailer connector could also be to blame. You will need to make sure the truck and trailer side connectors are clean and free of corrosion inside and out.

If the truck side checks out fine then it could be the wiring to the brake magnets or the magnets themselves. Inspect the power wires to the magnets and look for pinched, frayed, or damaged wires and fix as needed. Make sure the ground wires are attached to clean and corrosion free bare metal surfaces.

You can visually inspect the magnets and if you can see the copper windings coming through the magnets will need to be replaced. To further test the magnets you can follow the help article I have linked. I have also included some help articles on testing and troubleshooting brake controllers for you.
