Lighting gauges: proper spot to splice into dash light power?

I know this is an old thread - but just thought I would mention that if you are going to run a voltmeter, make CERTAIN that is has a fuse in the supply line. Otherwise, should you have a failure, it can leave your wiring a "hot mess"!! (nothing like an unfused hot wire grounding out - 12 volt welding anyone???)
