Can someone post a pics of J1 on the squawk and talk board? My new-to-me centaur has no sounds. My J1 looks pretty hacky. From the circuit diagram, I should see pins 16, 17, & 18 used, but I don't even seem to have wires for them. My J2s on squawk and talk and the say it again are pretty hacky too.
I wish there were wire colors in the diagram.
