Does anyone know if there are any differences in the 03-05 main gauge cluster and the 06 one other than the face of the tach has higher redline? If the gauge actually goes to a higher RPM then I would think that they are not compatible. If the amount of RPM the gauges show are the same just the actual redline on the face of it is different, then it should work.

I am assuming the plugs are the same in the back, but I am not sure. Can anyone post of a pic of an 06 cluster?
