A/F gauge hookup

On my car (eviljays delsol) there is a bolt where the o2 sensor would go on the down pipe. So no o2 sensor.

Can I go to autozone and pick up a generic bosch o2 sensor and wire that to the A/F gauge in the car?

Sorry if this is a stupid question. Kinda new to modded cars.

Yes you can
