Almost there!
Now you simply plug the white connector from the main harness as well as the tiny white connector from the long switch cable into the cruise control unit.
Tuck the unit and wiring into the available cavity as well as you can.
Using some bubble wrap to cushion the unit will help prevent any knocking you might otherwise hear when you go over bumps.
Now perform many of the previous installation steps in reverse to finish cleaning up:
- Finish tucking in the switch wire under the carpet.
- Put the rear passenger panel back on using the 5 clips and T25 Torx bolt (and don't forget the plastic bolt cover).
- Replace the upper steering column cover using the two screws and then position and snap the lower cover back into place.
- Reconnect the battery (it is normal to hear clicks and other sounds and your radio may come on), tighten the negative terminal with the 10mm wrench, replace the passenger foam insert (remember the black plastic nut), and put the carpet back and secure it with the plastic screw.
Done! Read the operating manual pages and go for a test drive!
