After further inspection, finally found the switch that is actually broken through continuity testing. It is the Right Trough switch. Other issue is: white-green wire is continuous between right trough and far left trough (both do not operate as intended, though the actual switch of the far left trough is functional). Both switches get properly triggered when jumping the white-green wire connection from another area of the playfield (right slingshot). White green wire seems to be connected directly to both right trough and far left trough as well
