Canadian Oshawa version O2 SENSOR

Hello,

I wish buying new o2 sensor but how to be sure for the avy version? 

Anyone have the response? On rockauto, all sensor are specified for Canadian or Mexican version?

Must be MExico as trucks were made there....

 
News from rockauto, to determinate the origin, just look on driver door jam, there is indicated with tire pressure and some information.
Mexico
I bough from ngk, http://www.ngksparkplugs.com/part_finder/car_truck_suv/results.asp
