The holes for the tri-colored lights are on the panel and labeled, but
there is nothing behind them. No led's, no wires... Is there an
entire daughter board that runs the MB's? I may be biting off more
than I can chew, but looking at pics of other Cessna audio panels
on-line, it just looked like there were led's and wires running to the
main board, but it was hard to tell...

I've got the Marker Beacon receiver out of a Tomahawk if you need one,
don't have the pin outs for it though, its a TKM unit...
