Steering Wheel Spiral Cable Pin Out?

Planning on putting some more features on the steering wheel and I'm investigating the availability of spare conductors in the Spiral Cable. I've found all the existing button wiring in the schematics except the "Radar sensitivity" and the "Lane Departure" buttons below the radio controls. Any idea where I would find what systems control the Radar and the Lane Departure? The Air Bag wiring does not seem to go through the S8 14 pin connector that supplies the buttons.

One of the modifications will be a momentary push button to activate the windshield wiper. Yes, I am lazy, and I have done this to another vehicle in the past.

 

Bump!

I know its not what you are looking for but maybe it will help

 

Sounds like your EWD is for the 2016-2017. You'll need the diagram for 2018+ (that's when radar cruise was added). I think I have it on my computer. Bother me via PM tomorrow afternoon since I'll likely forget.

 

Thanks. Now these are the type of mods I like. I noticed you posted on the first page of the thread you linked. Did you ever make this mod to your 2nd Gen?

 

yes sir .

PMed.

 

Hope that got you what you needed

 

Thank You found the last wiring and pinouts.

Will see if it matches the vehicle when I go exploring.
