uhh, like the title says.. will just the tach swap into the gauge cluster? I want to keep the rest of my TII gauges if I can, though all s5 gauges would be fine I guess, I'd deal with the lower speedo.

 

you cant swap the tachs out anyway if you could becuase the guage cluster is all one assembly and you would have to take it somewhere and get the tach recalibrated and all that. but if you have a nother gauge cluster thats from an s5 and you have an s4 then you could always re-wire the plug connectors so the s5 guage pod will work. its easy, theres a write up on here somewhere that tells what wires to splice into what wires...

 

wrong ^^^
the gauge cluster is not all 1 assembly

it has 4 sections... wiring is a different story

rotaryrescurection has a write up on putting a s5 guage clutster into a s4 car... go ahead and read that.
