I took some readings off the metro map sensor that coyotex sent. I used an atmega168 to turn 5 volts into a 0 to 1023 number, but a voltmeter on 5 volt scale would do fine too (for a geo):

I really have no idea how many cars use pulses vs sensors or what all the pinouts are or the signals or voltages involved might be though.

Oh, and an analog meter would be nice for vacuum.
