I had an old GE electric cooktop that I'm replacing with a new Whirlpool. The old cooktop controls are on the range hood. there are 19 wires at the connection: 5 red, 5 white, 4 yellow, 4 black, and 1 blue. (see photo) I started to cut the wires before figuring out how to do it. the new cooktop has 1 black, 1 red, and 1 copper wire. How in the world should I wire this up? Any help would be appreciated.
