I recently unplugged mine with excellent results. I now wonder why the'duty cycle' still acts the same. Steady 45 degrees until warmed up, then fluctuating between 40 and 50. Just like the O2 was plugged in.
the connection you need to pull apart is round and located just under the fuel filter and the fuel accumulator. The connector to which it is plugged pokes straight out toward the engine, and you'll pull toward the engine. You'll probably have to remove a hose or two.
