Notes:

  • Some Bose amps have a GRAY connector instead of a BLACK connector. This harness will still work with your gray connector. It will have an offset tab, we will cut one of the tabs on our harness to fit your vehicle. If your harness has both side tabs please note the LEFT tab needs to be trimmed. 
  • Some Vehicles don't have a BOSE tuned amplifier but DO have a factory amplifier that use this same harness.
  • Harness ordered with an LOC/Processor includes a remote turn on cable. 
  • Chimes will not be affected.
