Sorry, new guy here, very unfamiliar with the details... I tried the search, but couldn't get it to find anything... so, I'm sorry if this is already posted somewhere...

I have recently aquired my wife's '03 EX Coupe. It has the gauges with chrome and lighted orange rings around each gauge, and all the radio, A/C, etc light up orange. Well, I have seen pix of an 04 with chrome rings, but lighted blue rings. Are the radio, A/C, etc controls lit up blue then? If so, is it a direct swap from orange to blue gauges from one EX to another? and are coupes and sedan dashes all the same 01-05?

Also, where can I find all the letter designations for different models and engines. I see most people refer to cars by what I'm assuming are factory codes as opposed to years and models...

thanks...
