how to replace control panel?

Here is my Kenmore Ultra Wash diswasher # 665.1358. It is about 16 months old. One day it did not get started. A technican came and determined the touch pad failed. He ordered the new one to have it delivered to our home. We have the new touch panel. However, Sears broke their promised repair day. We cannot wait another two more weeks. Please tell me how to install the black panel. It is nothing inside execept some kind of circuit strip.
Thank you for your support. I cannot depend on Sears any more. Harumi
