Hello all I am new here and could use a little bit of help. I recently upgraded my I03 system in my 15 Tahoe. I’ve gotten everything else completed but I have yet to get the steering wheel controls working. I was told I needed to connect to the green/ black swc wire on my aftermarket radio the green/black wire lan wire ok the truck. However after reaching out I’ve gotten several different answers as to which wire I need. Can anywhere tell me for certain where this wire or post some pictures for me? Thanks all help is appreciated.
