The left side one is the only one that changes from that pic on the website. Home button is gone and voice control is moved to where the Home button used to be.
My only thing is both button packs are a different part number from the 22-24 Si so I don't know if you will be able to control the cruise functions with the new cluster.
Same size 32 pin connector but the only difference I see is in the number 2 spot on the 22-24 Si is a green wire for the CMBS (Collision Mitigation Braking System) and on the 25 Si harness that spot is empty.
What does this mean? Will it still function just an error code on the cluster? No idea until someone tries it I suppose, just adding more information.
I'm still waiting for one to show up locally so I can see how the layout has changed and how you switch stuff with the steering wheel buttons. Actually, shit, the Integra already has all this shit. I'll just go next door and look at that layout.
Turns out the whole of Honda Sensing is controlled through the scroll wheel on the left side control. We don't have that on the Si so you were right we need both the left and right and the harness for it. All the controls you don't get on the left one are on the right side of the digital cluster. We don't see that because the cluster is half analogue. With the full digital the left side is for audio controls and stuff like that and the right side is for vehicle controls.
Sorry I meant to type right side controls on the steering wheel. There is a scroll wheel on the right side now that controls the right side of the cluster.
