My grandpa is full of c***.

I hooked it up to the big trailer to test my controller (that wasn't working?), well turns out, my grandpa was wrong, the light only comes on when it is plugged into a trailer. Lights worked, and we could hear the brakes actuating when I pulled the manual lever.

Oh and this is my buddies 2500 24 valve cummins, I didn't realize how different the cummins looked/sounded then the powerstroke/duramax. I like the cummins how it isn't as crowded under there as my truck. It sounds nice though. The only reason he isn't using his truck is because mine is black. (Or maybe his truck can't pull that big trailer!)
