What it does is space 2nd O2-sensor further away from exhaust-stream so it has different reading than 1st one. But yeah, your idea of leaving it out of exhaust altogether should work as well. The ECU just compares signal from 1st & 2nd and if they are too similar, it thinks catalytic is failing.

Only output from trans is VSS pulses that goes to dash to drive speedometer. That can be left disconnected.
