Celica Forums General Discussion Exterior gauges instalation?

Can someone tell me how to install the voltometer and the air/fuel presure gauges??

I connected my voltmeter to a wire that I tested under that dash that had a 12v source to it whenever the key was turned to ACC and when it was started...
for the lighting part of it, I tapped into a illumination wire under the dash that was for an option I did not have...so basically it was a lonely connector...I'll get full pics tomorrow.

Volt gauge sounded fine, i did it differently, but what ever works ya know? and as far as the air/fuel ratio, you have to tap into a blue wire (on my 00 GTS it's blue) that runs under the carpet, on the passenger side of the car, below the fuse panel, it runs along the vertical part. if you have any other questions let me know!

does anyone know where the wire is that you have to tap into for the electric water temp?
