Okay, I have to confess. It's a BS gauge.
I started the project and like Josh said when he worked on his, it's almost impossible to make it look like the Maxima one...

I got a little frustrated and just decided to make it for show. I tore it all up so it doesn't work it's only cosmetic. I have probably 20+ LED's in there to make it glow. Nothing but the faces, needles, and the housing is what you see. I figured when I wanna go to a show or something I can pop my working one out and throw this in there.
For those who want to do it though, take it from Josh and I who have done it. Don't unless you have mad skills otherwise you're gonna mess your cluster up. Stick with changing the 194 bulbs and keep it clean.
Like how I gave myself a full tank of gas though?
Thanks for the comments, it was a cheap like $30 experiment.
