7. Here is the wiring diagram that's provided. The two 14-gauge wires coming from the rod need to get soldered to the two 14-gauge wires from the transformer. On the other side of the transformer there are two 18-gauge wires, one black and one black with a white strip. The solid black goes to the ground and the B/W goes to the yellow wire for the on/off switch. The black wire from the switch is ground and the red wire is positive with a 10-amp inline fuse.
