I definitely haven't done enough research on this, so I'm confused about one thing: How do the cruise control buttons function? I had ASSumed that the cruise control buttons would use the same communications bus that the audio control buttons on the steering wheel would use, but apparently that's not the case.

Do the cruise control buttons also use LIN, but go to a different LIN master controller than the audio control buttons? Or are the cruise control buttons communicating directly on the CAN bus?

From what you guys are saying about having to switch to the expensive gauge cluster, I'm guessing that the gauge cluster is the LIN master controller for the audio control buttons, which would then send the commands out on the CAN bus for the audio system to digest.

Either way, I still plan on sniffing the CAN bus on my friends LT truck to see if audio control button codes can be observed there.

They operate separately, so does the heated wheel. You need to run a wire from the cluster harness plug to the clock spring. Also need tho a better cluster if you have a custom.

Well, that wasn't the level of technical information that I was seeking.

Yes, I understand that you needed to run a wire from the cluster harness plug to the clock spring on the steering wheel in order to make the steering wheel audio controls work with the upgraded cluster that has been reprogrammed by White Automotive.

I was hoping to learn about how the audio control buttons differ from the cruise control buttons in terms of signal topology.

I'm guessing that the cruise control buttons and the audio control buttons are both LIN devices, but attached to different LIN controllers.

Since pin 9 on the clockspring controller seems to be connected to the LIN bus for the steering wheel audio controls, I'm hoping that I could create a standalone LIN to CAN translator device to read the steering wheel buttons from that pin 9, and send the correct corresponding CAN signals to the audio system (after somehow connecting to the CAN bus). That way I would not need to purchase the instrument panel upgrade.

Well jimbo, I dunno what to tell you. I never looked at how the stuff that already works worked...lol. I just know what I needed to do to get what didn't work to work...lol

I did a few changes in the last few weeks, I picked up a set of gm new trailboss ranchos, trailboss cv shafts, 2.0 trailboss leveling kit , 2.5 rear blocks and xl9000 rear shocks.

Removing the icon stuff wasn't the original idea but the current setup rides pretty nice and it looks good. Yes it handled and felt more controlled with the icons but its pretty soft and smooth now.

The new truck looks good! I have never heard of a TB not having the TB bed sticker. Interesting.

I miss not having some features of the LT, but I liked the front end looks so much better on my Custom TB. And the price difference was substantial....

I do like the look of the front end of the Custom! Also, I found a thread on taking the Trail Boss sticker off the bed. I thought it was under the clear coat and couldn't be removed. I was wrong.

The interior needed a few upgrades, I added a high country cluster from wams and a ltz steering wheel. Added a wire from the cluster connector to the clock spring ( harness dr) and now the stereo/phone wheel buttons work. Also changed the stereo bezel to match the steering wheel.

I did the clazzio leather heated seat kit, they fit super nice and as you sit in em more they fit better as you can tighten them. This is when I 1st installed them.

Did you get the heat button to work on the steering wheel?

No, ran power to it and the switch doesn't light up and the wheel doesn't work.... sorry... its a shame since everything else works.

From the little bit of research that I did as seen here:

It appears that you'll need to connect the LIN Bus 19 line. It needs to run from the X85 clockspring connector pin 10 (Circuit 4119 GN/BU size 0.35, LIN Bus 19) to K33 HVAC Control Module X2 pin 6.
