I have a 1998 Protege and I have to replace one of the o2 sensors with a three-wire design.

One of the sensors is close to the exhaust manifold and has three wires on it, while the other sensor is further down (closer to the oil pan) and has four wires on it.

Can I adapt a four wire sensor toreplace a three wire sensor?

I happen to have a spare four-wire sensor and I was wondering if I can use it for this repair.
