My first time here! I am going to wire in some bed lights in my 2012 F150 Supercrew FX4. I am planning on hooking into the trailer harness but am not sure which is the hot wire. Can anyone tell me which one it is and the ground or point me to a diagram for the 2012 harness? Does anyone have a better place/idea where to attach the wires?

Thanks
