I bought a used cooktop (elec, 5 burner, 1 of which is halogen) @ the habitat store recently. The cooktop does not have a cord on it. I took the cover off and it appears the old wire was clipped. Is it difficult to add a new cord? I was expecting some sort of connection plate like on a range or dryer. Can I use the cord off of the 5 burner GE cooktop I have now? Thanks.
