First, get the car up to normal oil temperature by going up on the freeway and stomping a Mustang. (That last part is not per the manual).

Disconnect the O2 sensor plug connection on the left-hand side at the rear of the
engine compartment.

On the SENSOR end of the plug, check the voltage between the terminal with the Green wire and engine ground. It should be in the range of 0.1V to 0.95V. If it is running rich, it should be somewhere around the 0.8V to 0.95V range.
