You need to look at a wiring diagram to be sure. The 2 white wires are probably the heater circuit. I would guess that grey is the sensor wire, but like i said, check a wiring diagram before you fry your gauge.

Or you need to just probe the wires untill you
find the one making voltage when it gets hot.
The best way to hook up an air fuel meter is
on its own seporate o2 sensor they will be more
acurate.
I run the nordask anolog meter on its own o2
and compairing to a wide band o2 on a dyno its
closer that I ever thought it would be
You do have to drill a hole and weld a bung into
the exhaust system to install the second o2 I put
mine about 6" in front of the factory one
They are nice to have while tweaking out a comp
controled engine being able to see what is
happinging with cyl temps, lean hot rich cold

One thing I forgot
You can go to a tech school or public library
and look in there mitchel manuals that have the
diagram and pick up the signal right at the comp
plug just use a scotch lock T conector with no
wire damage just clips on the wire with the wire
hooked in a T position and seal it with a little
silicon so no water or mosture can get in
