Stereo & Electronics - Stereo Controls wont work

I have bought 2 Trans Ams, a 2001 and 2002 WS6, and the steering wheel controls wont work on both, they dont light up or anything. Both have stock stereos, does anyone know much about this?

I cant find anything posted on this.

However they came from the factory

you need an aftermarket module to make them work. Do you have this wired in on install?

It is the bone stock Mansoon stereo that it came with from the factory, the same one that was in it at the dealership, its never been removed. The steering will controls just stopped working, but it has always had them.
