How to connect OBD2 on Kenwood 694s head unit

I am working on installation of Kenwood unit but would be great if someone can give me directions how to connect OBD2 on Kenwood head unit.

I have maestro rr with harness and all other connectors but run into the problem and couldn't find any information about how to connect OBD2 on Kenwood head unit in order to have reading gauges and tire pressure.

I would appreciate any help you could provide. This is my first replacement install and really don't know much about it.

Referring to tundra double cab sr5 2016

Thank you in advance

 

maestro rr has a cable that plugs into OBD2, then there is a data cable that goes from the maestro to the head unit
