Welcome to GMTNation! Here's a link discussing the adapters you may need to do this.

What a long story that is! Good luck but to point you in the right direction you would need to look into the GMOS-014 for maintaining rear controls.

Also check one of my older threads were there many debates and discussions.

They're tested with branded aftermarket brands but after seeing non branded ones in the market here they all have the same wiring in the back. I'd presume they would work but not certain since haven't tested it
