Hello,
I have an 06 monte carlo, wondering if anyone can help with with the factory wiring colors. It does have steering wheel controls, I can't find the correct diagram stating what colors are which and go to what. I have attached the wiring from the car below.

Thank you,

 

Good Day, Welcome to the forum. Hopefully you will find the answers to your question here

 

The best way to find that is to search for a Service Manual. That said there is a link in this forum that refers to Service manuals that you could check.
