2011 Chevrolet Impala LT Stereo Wiring

I need a stereo wiring diagram for a 2011 Impala LT, nothing I was able to find online quite matched what my vehicle has.

To be more specific about what I need, the below website has been helpful in identifying some of the wires but not all of them.
https://my.prostreetonline.com/2016/09/07/chevy-impala-stereo-wiring-diagram/

Here's what I actually have, and my guess at their purpose using the above guide.

Wire      - Purpose
Red w/ White stripe      - Constant 12v+
Black w/ White stripe    - Ground
Tan       - FL+ (Front Right speaker positive)
Grey      - FL-
Light Green              - FR+
Dark Green- FR-
Pink      - Amp/Antenna trigger
Dark Green w/ White strp - ??

Brown     - RL+
Yellow    - RL-
Dark Blue - RR+
Light Blue- RR-
Baby Blueish?            - ??
Orange w/ Black stripe   - ??

There is no Purple/White for the dimmer like every guide I found mentions
