Bottom oven burner burned out (clear separation in element)

Removed 2 screws that hold the element in place. I then pulled the element out 3-4 inches and noticed 3 wires attached. (had expected 2). Disconeccted the 3 wires and renoved old element.. Reversed process with new element, and reattached wires as I found them. Inserted element and inserted holding screws for new element. Ran through self-cleaning cycle. Works great. A written warning about the wires in the box would have been comforting.
