That's great news Rick
For the end cap im gonna need some info, Using the following image https://www.partswebsite.com/stores/...sT/TM09620.gif
# 13 is listed as a control panel but is not serviced
If we are looking for #12 your VIN shows you have a media hub option (RSF). Are you looking to retain this option and add the heated seat switches to the panel?
