After searching, looking through wiring diagrams, searching some more, comparing clusters, and then searching some more, I can't seem to find anyone who has swapped the S4 warning light cluster to the S5 one. It seems to me like you should be able to re-pin it just like doing a gauge cluster swap, but I don't know what wires to move. Has anyone else tried this or is just me that thinks the S5 looks better? Any thing would be helpful at this point, I'm just stumped.

 

A late S4 set of warning lights would probably be easier, and they look the same as the S5 version.

Don't mind the obvious modifications in each of these examples.

 

That does seem easier, Did all 88's come with that or just some? My parts car is an 88 but I don't think it has that one.
