I have a 2011 Camaro rs 3.6 liter I知 doing an engine swap. I知 putting in a gen 4 ly6 6.0 with a 4l80 transmission. Does anyone know exactly what wiring harness I need to keep everything working the way it is now? Windows, radio, air conditioning etc??

 

The windows, radio, air conditioning, etc is most likely controlled by the body control module. As long as you keep that intact, it should all still work.
