KitchenAid K5A wiring

KitchenAid K5A wiring

I have opened the motor head assembly and see several frayed wires. I need video help or a repair manual to show how to disassemble and replace wiring. Any ideas on where to get help? 

I am familiar with repairing gears as I have done it on newer models.

I also read a suggestion about replacing the controller with the K5SS one.
