Does anyone know if the cluster hoods are interchangeable? I know the wiper switch and cruise switch are different, but I assume they mount the same and the s4 switches can be installed into the s5 cluster.
Thanks!

 

Somewhat. I currently have a S4 in my S5.From what I recall the wiper and headlight switches mount just fine. The turn signal I don't think did though I can't remember now the details. They are slightly different in that area. My( s5) signal doesn't sit flush with the surround. It sticks out some. I imagine a s4 in a s5 would be recessed some into the surround. Whether enough to interfere with the signal lever's function I don't know. As for the cruise I don't have it, but the block off that goes into the empty spot had the same problem so I had to glue in a piece of plastic there. From this I gather the cruise switch would have a similar problem to the signal one.

 

the turn signal/cruise switches have slightly different shapes, so they go in and work, but don't fit exactly right and you can see it
