i think eventually i would like to add aftermarket gauges. has anyone done this before? i would like to add a real tachometer (that tiny digital readout sucks, lets face it), an oil pressure gauge, and perhaps an amp gauge. some of the factory instrumentation is severely lacking. can the installation be neat (what to use for a gauge pod). i see where the oil pressure sender is, how to install a tach without having an ignition system to read pulses?
