The drive cable for the speedo comes off the left front wheel. It goes
to a black box just above the spare tire under the front of the van. The
counter in the box connects to the OX2 light. When the black box counts
to 60,000 (as I recall) the red OX2 light is turned on. That is all it
does....just turns the light on. This is a simple reminder  to change
the oxygen sensor at the catalytic converter. That is absolutely all
that light does.....reminds.

The second or upper part of your speedo cable comes out of the box and
goes through the front wall up to the back of the speedometer.

To reset the Oxygen light, feel on the top of the black box for a detent
button. Depress it and voila! The oxygen light should go out and you are
good to go for another 60,000 miles. But don't forget to service the
Oxygen sensor.

Happy detent depressing~~~ -{;<)>
