I'm wondering if anyone can confirm if a 2017 L405 without ACC still has the wiring harness for the radar unit? In pictures on 2016-, I see it's clipped right in the center of the cut out. I looked for this without taking the front bumper off but didn't see it. Not sure if it's still using the same wiring harness or not. Looking to retrofit ACC but don't want to pull the trigger on a radar if the wiring isn't there.

I am aware that GAP doesn't support CCF programming on 2017+ yet, I'm using Pathfinder.+ a CCF editor to push changes.

After taking off the bumper and thoroughly looking, I can confirm I do NOT have the wiring harness. I have the SE model so perhaps they have a couple different looms or switched just for '17.

This is a bummer as I removed the grille and tried to look at mine and there seems to be no loom either...

I don't know if this helps, but my 2013 Vogue has the wiring in place and was clipped to the cut-out in the crash-bar.

I've now fitted the radar (it needed a bracket, but very simple to fit - just plugged in) and added the switch pack to the steering wheel, but not got around to re-programming the CCF yet. Current:

It seems that for 2017 onwards the wiring loom is customised to the vehicle spec to a great degree which makes retrofitting things like remote climate and adaptive cruise a lot more difficult.
