What you mean is you want the american grill instead of the canadian DTRL
they both fit the bumper the same (bumpers are identicle)
Lots of people in america would love to have the DTRLs instead of the grills, so hit up an american board and set up a trade (Assuming you have the DTRLs)
As for install … they just screw in. You’ll have to figure out how to do the wiring … not sure if the american cars will have the harness for them or not. Doubt it.
To wire something up for them wouldn’t be too hard. I’d recommend a relay, a switch, and some wire. The rest you’ll have to figure out
