These wires let you keep your OEM aux jack to work with your new aftermarket radio. Grab a cheap RCA Auxiliary Cable plug either the aux or the rcas into the back of your new aftermarket radio depending on what type of audio input they have. Then cut off the other end and splice into the following wires at the 14-pin connector found behind the radio:
OEM AUX Audio Left Signal: White @ 6 pin connector pin 5
OEM AUX Audio Left Ground: Red @ 6 pin connector pin 4
OEM AUX Audio Right Signal: Brown @ 6 pin connector pin 3
OEM AUX Audio Right Ground Red @ 6 pin connector pin 4
Radio Size: Single or Double Din
Speaker Size Front: 6.5″
Speaker Size Rear: 6.5″
Speaker Size Subwoofer: 8″
Use the adapters below to install common 6.5″ speakers in the doors. Depending on the size and depth of speakers you still may need to cut some of the door metal away. Use some tin snips to easily get the job done.
Radio Removal: Using plastic bezel removal tools carefully pop the radio bezel from the dash. Unplug all the connectors and remove the dash bezel. The radio and pocket below is then held in with 5 screws.
Keep in mind if you are installing a new radio you need the mounting kit, the wiring harness, the antenna adapter, and the steering wheel control adapter if you have audio controls on the wheel you want to keep.
