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.

How long was the wait on the wheel?

Hey Flatblack..!

I have also done the steering wheel, I just received the wire to do the Instrument Cluster swap and have also ordered the new cluster from White Media, I also would like to upgrade some of my Dash pieces and including the Radio/Stereo Bezel, Do you happen to have the part number, and did you find it on eBay or an GM-OEM Online parts store.

A few days from the local dealer, my buddies shop has an account but this was almost a year ago.

The vin # they used for the steering wheel they used for the stereo trim piece. The color is synthesis, im pretty sure this is the # 23387904.

Thanks Flatblack, you know I have a Synthesis Center Bezel but the edges don't have the chrome color edgesd like they apparently did on the 2019-2020 Silverados as you can see from my Center Bezel, it is the synthesis with no chrome edges, can you confirm that your is different than mine, thanks..!!!

I'll get you a pic in the am, yours looks like what mine came with. Like a darker grayish color. Palladium I think it's called.

Okay thanks, I am intrigued by this puzzle, as I'm also interested in doing the entire dash just like this guy named Matt who has is own channel on Youtube called MonsterTek, and he gives the complete part numbers for most of the pieces on the dash that have the chrome look with soft leather instead of plastic, except for the Center/Radio Bezel.

Large leather dash pad for drivers side = GM 84420199

Soft touch leather upper glove box door = GM 84539639

Small leather dash pad for drivers side = GM 84266580

Instrument cluster visor leather = GM 84054788

After visiting some GM OEM online parts stores, I have found that apparently there are 3 different colors available for 2019-2020 Silverado and Sierra 1500s.

1. Bronze

2. Liquid Palladium

3. Synthesis

hey quick question, I have the steering wheel ordered for my custom, am i able to just plug it in and use the sterio controls, or do i have to buy the high country cluster off wams and connect the new wire?

You need the wire and cluster.

I'm debating do I want to do that swap, I'd rather the nicer door pannels too tho.

That's a shame that we can't add steering wheel radio controls without upgrading the cluster. Seems strange to me that the cluster would have something to do with decoding the steering wheel controls for the audio system. I really want the audio control buttons, but have no desire to change my gauges.

Maybe WAMS can come up with a way to reprogram the stock cluster to make the steering wheel radio controls work?

I bought hardware and was going to sniff the CANbus on my friend's RST to see if the steering wheel buttons just transmit commands onto the CANbus for the audio system. I was then going to try to replay those commands on my Custom Trail Boss to see if it will control the IOR radio. Haven't had time to play around with this yet though.

Flatblack83 · January 6, 2022

I doubt that will work, it needs the lin bus circuit for the buttons to work. With out adding the wire its not going to. That wire makes everything on that side of the wheel work. The only thing that doesn't work is the heated wheel, that's another can of worms.

The factory cluster won't work since its not setup for that, it doesn't use wheel controls since it has the dial.

I'd imagine the cluster from an lt would work but I'm not sure, you would need to speak with wams about. A programmed lt cluster from them would save a few bucks of they do it.

I know 1k is alot for just that to work but that cluster is really nice. Wheel buttons for the volume and the phone is what makes it..lol.. The best part I think is when you put it in tow haul mode the battery gauge turns into the trans temp. Pretty nice when towing.

I did a few more upgrades to my Double-cab Custom earlier this week. Before and after:

Oh wait, no... I actually traded in my Custom "looks like a TB" in on an actual TB! LOL

I liked my Custom and I had it looking about the way I wanted, but I got tired of hearing my teenagers complain about legroom and my 4'11" wife complaining about not being able to see over the hood when driving. So I knew I had to go Crew Cab and LT (adj drivers seat), but I decided to go all the way and make it a TB too. About the only mods is de-badged, tint and muffler delete. I already have Westin HDX steps on the way... Anyone know the story behind a TB with no TB bed sticker?!?!

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?

** edit ** - Looked at the gmupfitter documents and I see that the cruise control buttons are on a separate bus, and connected to pin 11 on the clockspring (X85 X1) connector. And I see that the audio controls are on LIN Bus 12 (pin 9), while the heated steering wheel is on LIN Bus 19 (pin 10).

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. ** edit ** - Apparently the gauge cluster is the LIN master for bus 12, but the data is actually broadcast on the vehicle's Ethernet bus.

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.

Added info I learned from the gmupfitter docs

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....

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.
