Re: Adding OEM fog lights
Start pulling it apart. Most of the time anymore, there are not too many instances where wiring is supplied from the factory for options the vehicle doesn't have. Assuming the underhood fuse block has the required terminals for the relay and the fuse for the fog lamps, you need to run wiring to the BCM, for relay control, you'd need a switch, part of the headlamp switch by the schematics, and then the wiring to the lamps themselves. Then you'd need to have the BCM reprogrammed for the fog lamps as well. That might be the hard part. Never tried it outside of installing a factory accessory kit. There's an authorization number that comes with the kit and we use that for getting the software changed. Now this would be what I've done in the past for a Cruze. Cruze no longer needs that programming so maybe the gen 8 Malibu BCM is ready to go, maybe not, I don't know that, never been down that road. The wiring you need to do is all fabrication, not factory harnesses.
