It comes out of the engine harness with the fuel injector plugs. The wire will have a single-conductor square plug on it, and you'll find it up at the backside of the intake manifold, at the back end of the fuel rail.

It is actually a black wire (and you may see a grey outer jacket). The color code thing is funky with the shielded wires (like the O2 sensor and part of the tach pickup for the ECU). The connector is mostly rectangular looking (round in the center). It will probably look like a discolored white (yellowish) and is about 2" long or so.

This car is a GSL-SE, correct? The 12A powered cars do not have an O2 sensor.
