Electrical manual / pinout request.

Car: 2015 jeep cherokee

Hey, I have been mainly monitoring all of the forums for a while, and I have been using the information a lot, I only have a new problem with a dashboard with sometimes the panel going out, I am suspecting an issue with a voltage on the connector to the odometer, I searched on the forum and looked around for Service Manuals for it, but I found good ones only until 2005 (pacific coast) but none for the latest (and since the hidden service page is hidden again, can't look on that), it's a 18 pin connector. So does anybody have a site with the service manual with electronic diagram or just the electronic diagram of the odometer?
