Questions about this item

What GM steering-wheel-control vehicles from 2004 to 2012 does this T-harness fit?

The ADSTHRGM2 is built for select 2004-2012 GM models that came with factory steering-wheel audio controls; verify your exact vehicle application before purchase.

How do I install the T-harness and what step is most often missed?

Plug the harness between the factory radio connector and the vehicle wiring, then connect the aftermarket head unit; the step most installers forget is securing the steering-wheel-control wire to the new radio’s SWC input.
