More mk1 findings

[jdbubb@ix.netcom.com (Dan Bubb)]

The O2 sensor reset box wires go to the dash to trigger the warning
light, not to the O2 sensor itself. Really it's just a mileage counter
that turns on a light after XXX miles.
On an irrelevant side note. I don't believe there is such a thing as a
two wire O2 sensor.

My 84 came with a 1 wire from the factory, so I'm thinking anything
earlier would be 1 wire.
