So if an SR comes pre-wired, why the need to purchase the steering column switch you mentioned earlier? Wouldn't you just need to connect the lamp and turn on your low beam for power? I've got the fog lamps, bezels, & wiring harness, all from chinese nissan parts place, but no combo/multi function/steering column switch. I can do away with the harness, cuz im pre-wired, but came here to find answers on the switch.The issue the OP is going to have is the standard S base is not pre-wired for Fog Lights so he will need to do all the wiring. The SR is the only one that comes pre-wired as they are built along with the Platinums.
