Hello All,
I have a few questions in regards to integrating steering wheel controls into a 2014 Silverado WT model. This truck belongs to my father and from what I can tell it has the IO4 factory stereo, what we have done was removed the HMI module and screen and installed an aftermarket deck (Kenwood DDX6903S) and a Maestro RR module to retain factory features. Since he wanted steering wheel controls we have swapped the steering wheel to one that has cruise and stereo controls (not heated).
Everything works as expected except the stereo controls for the deck. The cruise buttons work but the illumination on the buttons does not.
I have read through this entire thread and decided we needed to try running a wire from pin 20 on the cluster to pin 2 on the clockspring harness. I was hoping this would solve our issue but alas it doesn't. Since the maestro module just taps this wire at the clockspring I don't understand why this wire is needed but with all the data buses and electronics I figured it was worth a try.
One thing that was apparent when reading this thread was all the changes were done with a cluster swap. So I'm wondering if the WT cluster doesn't support a steering wheel with stereo controls and isn't programmed as such and could possibly explain why illumination doesn't work. I cant quite explain why taping the LIN bus for the maestro doesn't tho. Unless the steering wheel needs to be initialized or something first.
So being at a dead end I thought I would post here.
Would getting an upgraded cluster from WAM or similiar place solve the issue and get the illumination and stereo controls working?
Thank You,
Michael
