Gauge Clusters

I like haveing gauges over "idiot lights"..

One of my college professors had some great advice on gauges;

You want to pick a gauge that has a 270° sweep over one that only has a 90° sweep as it will be more accurate since it has a wider range of sweep for the needle...

A gauge is most accurate in the center of it's sweep. Meaning it is the most accurate at 50% +/- 25% (In the middle) and is less accurate at the beginning and end 25% of travel... Try to pick a gauge where it will read in the center of it's sweep for what you are measuring...

When I hook up aftermarket gauges under the dash, I like to use the circuit with the orange wires for the gauge lights so they can brighten and dim with the dash gauges...
