The easiest would be if you're willing to use the oxygen sensor LED.  many
people have bypassed them with a longer speedo cable anyways since its just
a mileage counter, and the box is just an extra source of potential
bouncy-needle speedometer syndrome.

In that case, the wire is already coming out of the back of the dash off
the connector, you just need to cut it and hook it up however you want it.
(Check the bentley for whether grounding it turns it on or off---I forget).
