I am in need of a valid wiring schematic and possibly a wiring harness for an older model Jenn Air Range/oven (D120). I would like to salvage this venerable unit and possibly use it in a home improvement down the road.

The wiring insulation has started to fray and the metal fatigue on the lugs has caused two to break away from the switches. I have extra switches but no wiring nor schematic. Any help would be appreciated.
