2015 Ram 2500 - Boss Wiring Removal Issue

Since I'm selling my V-plow, I decided to remove the plow wiring today. The only wires left connected to the pickup are 6 wires running underneath the fuse box which I'm assuming are for the headlights. I went to turn the headlights on just to see if they'd come on and nothing....the whole pickup is dead. There were only 2 wires running to the battery. Anyone have any idea what would cause my issue? I will admit I'm far from an electrical expert but I didn't have this issue when I removed the wiring from my other pickup. I'm stumped.
