If a regular inexpsensive harness is used you must run your own accessory wire, for the radio you are installing, to the fuse box or accessory wire at the ignition harness since this vehicle doesn't use an accessory wire to turn the oem radio "on". This oem radio turns "on" by means of data. Also, the factory door chime will be disabled when removing the factory radio unless you purchase a specific harness/module to maitain it working.
