SWC

[D_Wes]

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.

Pics of the truck, please.

Call Crutchfield, advise them specifically on what you've got in the truck, and they will recommend an interface module that will resolve your issues.
