Car Never

Will an oem fog light replacement fit my car even when my car never came with fog lights from factory?

The fog lights are for my car, I have a 2002 Mazda protege lx. all though, my car never came with fog lights, however my car's bumper has the openings to install these fog lights. But will i be able to complete the wiring and get them to work on my car?

you may well find that your car has the wiring loom to fit fog/driving lights the reason for this is cost cheaper to make all the same rather than have several different looms just a case of locating where the plugs are hidden and then away you go
if not there you will still be able to have the lights wired in to your car but for safety reasons have them wired to a fuse and a relay
