Brake light switch is mounted behind the brake pedal, you'll see itWhere is the brake light switch?
Where is DME connection at A60004 pin 23\
Where is EWS Pinout #8
Let me take pics of the DME connection. Cuz explaining it won't help
EWS pinout #8 is near the pedal assembly, you will see it. It's a white box that says EWS on it. Pinout #8 is one of the empty connectors on the wiring harness to it. The pinouts are numbered.
Let me take some pictures of the wiring really quick... Give me a couple of mins
EDIT: added it to the DIY
