Yup. I did a wiretup on this a while back and found it in the archives:

 Note in this picture (
http://198.107.18.114/V8Q/pics/RPM-Sensor-Conector(Bottom).jpg) there is a 
rouge green wire; this is the extra (chassis) ground that I used on the Bosh 
4-wire sensor. I eventually grounded it to the engine block and haven't had 
any problems sence. The 2 white heater wires go to the plug called out in my 
photo as O2 sensor, and the black sensor wire goes to a single fast-on 
(spade) connector with a rubber boot just barely seen south of the 2 white 
ones.
 For me, the O2 sensor was a very easy job, but some people have a bear of a 
time breaking the O2 sensor loose if the previous installer didn't use 
thermal grease (supplied on all new Bosh O2 sensors).
Here is a shot of the O2 sensor in the X of the exhaust cross pipe:

one that goes to engine ground.
 Good luck Torrence,
