Where can I find Kenmore cooktop model 629.42979 wiring diagram?

Hello
The wiring diagram is usually inside of the stove folded in a corner, or get the manual at the link I have provided and call them and they will email you one.

Sometimes if you call the manufacturer of an appliance and have your model number ready, they will email you an diagram or mail it to you. I would not tell them what you are planning on doing, simply because of them not recommending doing this they may not give you what you need. Just tell them you need a diagram thats all. I've done this in the past and it was free, just depends on the company you are dealing with. Hope this helps, good luck.
