Found it now - assuming it's that little bugger deep in there?

So today I set about getting some of it installed. I only had one button from the factory for stop/start and the rest were blanks… I’ve got heated windscreen but that’s on the above section.
Removed the airbox, battery and battery tray to get access the ABS pump and wiring. I wanted to add Tyre pressure monitoring and have the option to turn the traction control on and off.
Fed the wires up behind the glovebox and through the oem rubber grommet and connected them up.
Rest went to the bottom to connect to the new buttons and to the body control module.
Coded everything in with VCDS and gave it a quick test, all fitted fine and illuminated… phew!
And when I press the traction button, it switches it off how it should, very happy!
To go over the buttons
Park assist - this is connected to a front parking camera (will be shown in future updates)
TPMS - this works to reset the tyre pressures and gives a warning on the dash when pressed as well as a warning if I get a flat tyre
Stop/start - standard on every caddy I think! still works how it should.
ESP - let’s you switch off traction or stability control so great if your wanting to hoon around or in deep snow etc
Heated windscreen - This has been relocated from the top to make room for the heated seat controls and in preparation for future digital controls.
Yeah hypothetically the digital dash would work on any caddy 2004 onwards
