PUMPKIN CAR STEREO SUPPORT CENTER

Hi

My 11-RQ1221E-US-A came with two different main wire harness.

The main difference I see is that one harness has fewer RCA's than others? The harness with fewer RCA's seems to have a couple of other connectors as well.


Can you please explain the difference between the 2 wire harnesses?

Hi,
These two kind of harness with RCA are just used for two different Audi original cable.
They are all just plug and play.
If your car has Bose system, then you need to follow the below attach picture and connect the RCA cable to make the Bose system work.
