How can I set this up??

Can I just hook the arduino to the rpm meter on my car? then hook up rgb led in the cluster then write the code to chane at redline?
Thank you for you help

Yes, that's how you could do that but from your question it seems that it is not a "just" for you.
How do you intend to connect the Arduino to the RPM meter? In modern car using the OBD-II interface to get the RPM values (ELM-327 is a good google starting point) is much easier than to get the signal from the RPM meter.
The / needs to be inside the brackets:

You can Modify your initial post to fix that.

Thank you for the replies! Originally I planned on hooking into the RPM gauge on the car. Now I plan on using the OBD-II Bluetooth you mentioned because it will be easier and it provides more information. But I got to thinking if I'm already hooked into the OBD-II can I also attach a screen to the arduino and have it display problem codes for the car when a check engine light comes on?
Sure you can, but I would start with the original project and add new features when the first solution is running.
