Product review (5 stars): Be very careful with the wiring.
Took me a few weeks to find the round tuits I needed to tackle this job, but I finally found one of them (the round tuits) and attacked the job. First thing you need to be able to do is read a wiring diagram, and have the ability to read between the lines to get the wires from the old style switch to the proper terminals on this new style one. I was finally able to assure myself that my wiring was properly connected when I found a review on an appliance parts website from a customer who installed the same switch and wanted verification that he had connected everything correctly. I had mine correctly connected, but for some reason the inner element wouldn't heat. Upon dissecting the cooktop one more time  I finally discovered that while reassembling the control box previously, the purple wire had pulled off of its terminal on the burner  without my noticing. Plugged it back on, and now the burner works like new (and my wife is happy).
