I have these on my '96 S14. I got my kit from www.importintelligence.com last year.
I have the install to it too, at
http://www.geocities.com/super240sx, except that the last couple of pix don't have captions. The pix might look crappy 'coz I got crappy camera.
BTW, do you guys know that www.importcarpartsplus.com is using www.importintelligence.com 's pictures? You can see the lettering of "importintelligence" it at the bottom of the gauge that says SR20DET.
Email me if you have questions.
