I got the new talkback board installed, basically reverse engineered the wiring. There is one black wire that was connected to a pin in the middle of the old tb board to "CON 1" on this board, which I think is the "PA Module": http://www.cbtricks.com/radios/rflimited/omegaforce_s45_hp/tour/graphics/dsc00104.jpg
I don't know where this black wire would connect to the new talkback board. EDIT: The schematic says "Pin 8" on the AMT board but I don't find it. The TB seems to work fine, works in all modes including PA, and actually seems to work a lot better than it did with the old board (before it took a dump). The internal speaker's not working but I haven't re-opened the radio to try and re-connect the plug yet., ext speaker works fine. Edit: Internal speaker plug is bad, speaker works fine though.
Thanks for any info.
