Hi SRB;
Welcome to the forum.
Depending on where the wire broke, you may have enough slack to strip the end, and replace the high temperature wire eyelet. If you don't have enough slack, you will need to get 14 gauge high temperature wire, and also a high temperature wire eyelet, that will properly fit on the end of the element. If you have to replace or splice the wire, you need to take off the back cover, and just follow the wire. It would probably be easier to splice it, than to replace the wire and the high temperature connector that attaches the wire to the power source.
Make sure the wire is high temperature wire.
