TAS5713 Nexus Q

I need help with pinout as I'm having trouble identifying the last three pins on the bus.

Here is a picture of the bottom of the amp with the bus at the bottom.

An externally hosted image should be here but it was not working when we last tested it.

Here are the pins I've discovered so far (via the TAS5713 datasheet).

Any ideas why I can't find those three missing pins hooked to the TAS5713?

Since this is a two layer pcb, perhaps tracing the lines is my best bet?

For example, top left pin looks like it is hooked into the chassis.
