Notes:

Some vehicles will have this unit but not have audio signal. If the green factory connector only has a RED and BLACK wire and no other wires and there is no BOSE logo your vehicle may have a none bose factory amplifier. Our bose harness will work for that.

Chimes will not be affected.

Great Harness! Super convenient! Ez install!

"Worked great for my 2024 Trailblazer ACTIV (no bose, no amp, no anc). I installed it in less than 30 min. I went w/ the WaveTech LinkDQ attached to the Elite 2ch T-Harness Accessory & it was perfect for bringing bass that the factory headunit rolled off !!"

Exactly what I needed

"The harness works perfectly. Install was super easy. The workmanship was better than I was expecting. I especially liked the little details like the color coded wire covers and the custom heat shrink with logo on it. It was built to order and delivered in a reasonable time. I will definitely recommend anyone looking for a custom harness to shop with you and I will be buying from you with my next upgrade"
