Ya, there's a pretty nice tutorial out there with pics by some dude, (I think if you looked online, you know what I'm talking about)

So when ever you take the gauges apart, you'll see the double LCD screen, and right behind that there's a litle "plastic" piece. It looks white, but when you shine light through it, it turns out to be green. So once you get that "plastic" piece out from behind the LCD, use some sand paper to remove the green stuff from the back of piece. Once you scratch the back surface, you'll clearly see the green color, get rid of it, it's evil! So then in step 3, he mentions that you need to put electrical tape on the back of that piece, and voila, you're done. Well I tried that, and it was just copletely blacked out, the tape was too thick for the light to go through. So then I tried to sand some of that tape off, and no luck there either. So then I got some broken tail light tape, which is red and very trancelusent, and put it on the back of that "plastic" piece, intead of the electrical tape. It worked great. And this is what I got.
And ya, Lil PZEV, I got a 2003 ZX5. Thanks YellerSVT.
