Fog Light Install - Help

:
Mazda, 2014 Mz2 S MT
I have some 3rd party fog lights. The plastic outer housing does not seem to want to clip in. Does anyone have any ideas or tips other than trimming it?
Also, I have the switch. Would I just need to remove the dash to place it on the left(USA) of the steering column next to the traction control?
