For the cluster it depends on the year of your car and the cluster, but you can always just do a Frankenstein cluster swapping the JDM/USDM guages into yours. That is what I did as I got a 97 JDM ITR and needed it to fit in my 00 GSR...not to mention the JDM ITR did not have the SRS plug/lights on it.

Once you go amber in your cluster you are going to want to do the rest of your dash as well.
