1. Some manifolds have a plug you can unscrew to install a single wire
02 sensor into. Lines right up in the middle of the second and third
outlets, samples all four cylinders, (kind of).

2. If you install the 02 sensor down by the cat or on the downpipe you
need to use the three wire 02 sensor(s), they heat up via the second and
third wires and are better in these (relatively colder locations.
