Just picked up an 08 1500 with the 4.7 in it. It has the 7 blade plug in the bumper, but when I looked under the dash there’s nothing hooked up to the factory blue plug for the trailer harness. Maybe I’m mistaken and that plug is just for trailer brakes? Thanks for the help.

Yep. There is a pigtail that plugs into that. When you buy the truck new it comes with that pigtail but you can probably buy one aftermarket too. Then you need to buy an aftermarket brake box (Tekonsha, Reese, etc) and connect the wires from the new box to that pigtail. Another option might be the factory integrated trailer brakes but not sure on an '08

Not sure if this is the specific one for your truck but this is what you would need
