I don't know. I never looked for mine. I had mine installed at Best Buy. The wiring harness I bought replaced the stock low beam headlights, hooks up to the battery, the ambient light sensor, and has an inline fuse. My BCM wasn't touch (or shouldn't have been). No error codes yet. When I leave for the morning, the 1st time I put it in drive, there is a moment of low beams dimming (less than a second) then goes back to normal.I have a 2019. Is it likely that BCM still has Fog Lights disabled? Cruise forums have it enabled by default from what I have read.
Stock low beam wiring taken out. Aftermarket harness installed at the fuse box - this feeds electricity to the low beams. Electricity for the fogs come from the battery with an in line fuse. Fogs on and off with low beam. Stock headlight switch (without fog light option) remains. No additional switch for fogs.I'm not following what you mean by "replaced low beam harness"
Are you saying it came with a plug that taps into the stock low beam lights at the bulb end? Or at the fuse box end?
I think I'll want to go the parking lights route as then you have a simple way to turn them in independent of the head lights.
