Sounds good. If I make my own TPS sensor from a pot in this configuration,
then I won't have any trouble getting ths signal into the computer, but what
about the map sensor.

What does the output from a MAP sesnor look like? I understand it is a voltage
between 0 and 5v, but how do you wire it up? Assuming I have a MAP sensor of
unknown origin, how do I go about indentifying the wires?

With three wires, and the probable fact that it is a voltage divider much like
a pot, I suppose I could work it out with an ohm meter.
