Action:
1. Remove the blank button in the switch compartment to the right of the steering wheel. See Figure 2.
2. Remove the lower section of the dashboard on the driver's side.
3. Remove the rubber grommet installed above the pedal assembly and make a roughly 3Omm cut in the rubber. See Figure 3.
4. Insert the wiring harness.
The connector should be at the switch aperture.
5. Connect the extra wiring harness' brown/white lead to the brown/white lead on pin 7 of the switch for the electrically heated front seat. Use provided connector P/N 95 60 012. See Figure 4.
6. Connect the extra wiring harness' black lead to the black lead on pin 9 of the switch for the electrically heated front seat. Use provided connector P/N 95 60 012. See Figure 4.
7. Fit the connector on the TCS ON/OFF switch and mount the switch in the dashboard.
8. Run the black lead on the air duct over to the far right-hand comer of the relay box. Secure with cable ties provided in kit. Make sure that the lead is not in contact with any moving part.
9. Lubricate the black lead with a soap solution and then fit it in the cut previously made in the rubber grommet. See Figure 5.
10. Fit the rubber grommet in place and seal it carefully. Use sealant provided in kit.
11. Unplug the ABS ECM connector.
12. Pull the rubber protective cover off the connector. See Figure 6.A.
13. Separate the connector. See Figure 6.B.
14. Insert the black lead through the rubber bushing.
15. Snip the cable tie (see Figure 7.A) and carefully drill out the cover for pin 25 (see Figure 7.B) using a 4.5 mm drill bit.
16. Insert the lead's pin in the vacant position for pin 25. See Figure 7.B. Tug the lead slightly to check that it is firmly located.
See Wiring Diagram.
17. Press down the seal.
18. Secure the cable harness in the connector by means of a cable tie (see Figure 6.A).
19. Refit the cover over the connector.
20. Fit the rubber protective cover in place.
NOTE:
Using a suitable sealant, seal extremely carefully around the rubber protective cover so a moisture barrier is formed and moisture cannot reach the connector.
21. Plug the connector back into the ABS ECM and secure it with the locking clip.
22. Refit the lower section of the dashboard. Test drive the car and check that the switch works as intended.
NOTE:
The TCS function can be disengaged by using the switch only at speeds below 37 mph. When the ignition is turned off, TCS disengagement is cancelled. Each time the ignition switch is activated, TCS tunction becomes active.
