Macintosh IIx trace help

Does anyone know where the right most trace beside UA15 and UB15 is supposed to go to? The one corroded with green goo. Is this the trace to adb power or something else?

If you're talking about the topmost corroded trace, it runs between the audio jack and pin 17 on UB11 (VIA 2). On the audio jack, there are two rows of 3 pins. So from the back of the board, it's the middle pin of the second row.
