O2 dummy sensor

Does anybody know of a good o2 dummy sensor for a 99 cherokee? When someone did the exhaust on my jeep they failed to leave a bung for the o2.... or even the wiring harness......

Im guessing whoever did the exhaust did not include a cat? You can use an o2 spacer but as mentioned above you will need to install the wires back to the downstream o2 sensor. If visual inspection is needed a dummy shell can be tacked on.
