This should clarify it better. The VCT engine is not rare rather it's the newest Zetec 2.0L design. The earlier 95-97 US engines did not have VCT therefore they are without the sensor to the passenger side of the engine. On 98 and up engines that got the VCT engine, they have this sensor along with the spark plug cover stamped VCT. You can remove the cover and the rubber boot pops out of the plastic, reconnect it to the sensor without the cover. Very easy to do as I've done it. I will probably keep mine off if I go with colored wires. FWIW
