The first step in replacing the digital radio Antenna Cable (Extension) is to eliminate the upper trim panel from the instrument panel (I/P) and disconnect the digital radio Antenna Cable. Open the i/p storage compartment fully to gain access to the digital receiver and disconnect the Antenna Cable from it. Trim the ends of the original cable, leaving the rest in the wiring harness assembly. For installation, route, and retain the new cable through the to the i/p, using the Antenna Cable clips (4, 6) to retain it. Connect the Antenna Cable to the digital receiver and then connect the digital radio antenna extension cable to the digital radio Antenna Cable. Finally, replace the i/p upper trim panel and close the i/p storage compartment.
