If it is a Cessna audio panel many came without hookups for 2nd com,
makers, etc. I flew many C-152's with single com and Cessna audio panel.
The audio panel has switch holes for more radios, but no switches in
said holes. The PCB has spaces for relays, resistors, etc. but no components
installed.

If, indeed, it is a Cessna audio panel, you can get another one from
Airwich Avionics. Or, you could toss it and get a better audio panel.
