11. Disconnect the smaller of the two connectors (2) from the traction system control module (N47) and open at rear.
12. Solder yellow wire (ge) from wiring harness (1) to green wire (gn) from chamber 1 of connector (2) using solder connector.
13. Solder black/yellow wire (sw/ge) from wiring harness (1) to green/white wire (gn/ws) from chamber 2 of connector (2) with solder connector.

14. Jack up vehicle at front until front wheels can be turned.
15. Connect battery, switch on ignition.
16. Use multimeter to measure DC voltage between yellow wire (ge), black/yellow wire (sw/ge) and ground. The yellow wire (ge) is for the right front wheel signal. The black/yellow wire (sw/ ge) is for the left front wheel signal with wheel standing still "0 V or 12 V" and with wheel turning approx. "6 V". A pulse signal should be measurable when wheel is turning.

19. Route tie-out from front fuse and relay box (F1) and to data link connector (X11/4) toward front to fuse box.
20. Install new terminal on red/yellow wire (circuit 30) from wiring harness (1) and connect to fuse 5 in fuse and relay box (F1) (fuse 5 must be protected with 25 A).
21. Install new terminal on black/gray/red wire (sw/gr/rt) and connect to fuse 13 in fuse and relay box (F1).
22. Open data link connector (X 11/4).
23. Insert blue wire (bl) into chamber 32 on data link connector (X11/4).
24. Close data link connector (X11/4).
