I have a 06 LS, no Onstar, no xm radio, just a plain oh single disk cd player. Can anyone help me out with this?
I hope you aren't gonna splice into that harness. Just buy a module and keep your chimes and won't have to splice into the car harness.

Chevy Mgr,

I have a question about the wireing diagram(s) I see above. I notieced there is a
11 D-BU 1796 Steering Wheel Control Signal (UK3)
.

Would this be a place where I would see a push of one of the radio steering wheel buttons. (Volume Up?)

Would all the radio steering wheel buttons be on this wire?

How are the signals being passed by resistance differences along this wire?

Reason I as, I have the GMOS-LAN-04. The harness currently doesn't have a wire in the plug at this location, so it isn't passing this information along, but I would like to add an additional wire and use it to pass along the steering wheel buttons presses.

There is a device that can capture this resistance differences when each button is pressed. I would like to use this with my Carputer.

Any suggestions on how I could pick up this signal if the above is not correct? I am trying to not make an cuts / splices in the original wiring harness.

Roger

If anyone is wondering where to tap into when installing a line out converter for the Lt hhr with stock pioneer speakers I would recomend using the low level audio signal from either the front 2 speakers or rear 2 speakers.

Check the date on this thread. It's from over 9 years ago.
Besides, ChevyMgr is not on the site anymore.
