Oxygen sensor wires

Unfortunatelly, I have an h22 obd1 OEM O2 sensor without a connector, only wires. There are 2 black, 1 white and 1 green wires. Which is for what?

I have no clue because that's not the colors listed in the helms...
But if I had to guess... the blacks are the grouds. I would guess the green is the sensor + and the white is the heater +

Yup, that's my guess also.

I was actually going to have to ask this soon since my wideband got in; good info!
