Does it have a 4 flat or 4 square plug?

Hi Justin it is a 4 square plug. Here is the picture from the Densoautoparts website:http://densoautoparts.com/find-my-part/vehicle-selection. You can put your car's (or truck) year. make,ect. and get the sensor's picture from clicking a camera symbol. Hope this helps. I am a big fan of denso (used to be nippondenso) parts. Quality stuff and not too pricey.

03 Chevy Monte Carlo downstream 3800 will it fit

It fit my 1999 Pontiac Bonneville with the 3800,works great

Does the sensor come with wiring harness and plug

No. Wiring the old connector was not difficult, but you must be careful choosing the right wires as colors were not the same as my 2003 Buick. More importantly, the output didn't match and I replaced it with OEM ACDelco that worked perfectly.
