15. Identify the pink wire with a green stripe (Figure 18).
CAUTION: The RH main harness has other pink wires. Ensure that the correct wire is selected.

Figure 18
16. Cut the middle of the pink wire with the green stripe.
17. Use a wire stripper to remove approximately 5 mm of insulation from the end of the wire that is closest to the front of
the vehicle.
18. Place the heat shrink tubing over the exposed harness wire. Slide the tubing away from the exposed end of the wire.
19. Twist the exposed copper wires together and insert them into the splice terminal on the TPMS harness. Use a hand
crimp tool to crimp the wires inside the terminal (Figure 19).
NOTE: Ensure that the crimp is tight by gently pulling on the wires. If there is any movement, re-crimp the terminal. If
there is any doubt whether the connection is secure, apply solder to the terminal. Typically no solder is required.

21. Use a heat gun to shrink the shrink tube. The shrink tube contracts as heat is applied.
NOTE: A small amount of adhesive might drip out of the sides of the tube while heating. The adhesive provides a water
tight seal.
22. In the RH trunk area beneath the electric park brake ECU, remove the tape to expose the 2 white harness connectors
that are taped to the RH main harness (Figure 21).

Figure 21

NOTE: The wire colors for the white connectors on the RH main harness are the same as the wire colors on the TPMS
harness:



Solid green (no stripe)
Green with a white stripe

23. Match the colors to insert the free ends on the TPMS harness into cavity 4 on the correct connector.
24. Perform a push-pull-push test on both wires.
25. Tape the green and green/white wires together.
26. Tape the green and green/white wires to the RH main harness (Figure 21).

NOTE: Steps 27–39 describe how to secure the TPMS harness, working from the rear of the vehicle toward the front. Pull
the harness taut before each step.
CAUTION: Secure that harness so that it will not contact anything that might damage the wires.
27. Use a cable tie to secure the TPMS harness to the corrugated section of the RH main harness, behind the section of
exposed wire (Figure 22). Remove any excess tie.

Figure 22 (TPMS harness highlighted)
28. Wrap the TPMS harness and the exposed wires on the RH main harness together using electrical tape in a spiral
pattern (Figure 23).

Figure 23 (TPMS harness highlighted)
29. Use a cable tie to secure the TPMS harness to the corrugated section of the RH main body harness, in front of the
section of exposed wire (Figure 24). Remove any excess tie.

wires on the RH main harness.
31. Near the rear of the 2nd row seat frame, use a cable tie to secure the TPMS harness to the taped section of the main
RH main harness (Figure 25). Remove any excess tie.

Figure 25 (TPMS harness highlighted)
32. Use electrical tape to secure the section of the TPMS harness that leads to the TPMS ECU to the section of the main
RH main harness that routes upward along the C-Pillar (Figure 26).

Figure 26 (TPMS harness highlighted)
33. At the base of the C-Pillar, use electrical tape to secure the TPMS harness to the main RH main harness (Figure 27).

34. At the rear of the charger bay, use a cable tie to secure the TPMS harness to the main RH main harness
(Figure 28). Remove any excess tie.

Figure 28 (TPMS harness highlighted)
35. At the base of the sill panel between the HV cables and coolant hose, use a cable tie to secure the TPMS harness to
the main RH main harness (Figure 29). Remove any excess tie.

Figure 29 (TPMS harness highlighted)
36. Directly behind the RH front row seat pretensioner, use a cable tie to secure the TPMS harness to the RH main
harness. Remove and excess tie.
37. Directly in front of the RH front row seat pretensioner, use a cable tie to secure the TPMS harness to the RH main
harness. Remove and excess tie.
38. Use electrical tape to secure the TPMS harness to the harnesses inside the B-Pillar.
39. Push the harnesses completely inside the B-Pillar and cover the hole with the butyl patch.
40. Install all components that were removed for access and reconnect electrical power.
