aftermarket fog light installation

i have a 1999 g20 and interested in installing an aftermarket fog lights. i have the small rectangular piaa fog light. i am having a hard time bringing in the wire from the engine bay to the inside of the car where i want to place the switch near the air conditioner vent.

also, i was wondering how people are placing the brackets on the bumper. i have the oem bumper and don't want to change it. is there a secure way of installing it on the bumper.

thank you in advance
