Forget dwell. Duty cycle generated by the Lambda box to control freq valve is the end product of the lambda system. It's way downstream of the O2 connector.
Voltage. Different story. You should see it.
I would get a not so fat wire. Strip it back an inch or so and squish the strands into the O2 sensor female port using the male pin coming out of the clapped out connector. A back pin.
Start car and wait a minute to warm sensor and you should get a reading on the other end of the wire of less than one volt DC when MM is taken to ground. 0.9V I believe is the max if sensor is working.
