Where are Wi-Fi & Bluetooth "Connections"?

Where are the physical connections for the Bluetooth and Wi-Fi radios on the main logic board?

Dis-assembled my MacBook Pro Unibody Mid 2009 to clean up stuck keys and track pad. Re-assembled.

Now I see the following: "Wi-Fi: No hardware installed" and "Bluetooth: Not Available"

Sounds like perhaps one of the many ribbon cables did not get reconnected correctly or may have been damaged in the process.

So ... I am trying to determine which of the many various ribbon cables (and specific pins, if multiple functions are on a single cable) are associated with the radios.

This will help to to narrow down where to look to solve my problem.
