Right side O2 sensor. Shoebox has a "clickable" photo of a 95 wiring harness, and it clearly shows that connector in the same bundle as the starter, PCM ground, and knock sensor wires.

Great resource, best place to look for basic info like this.

Thanks for the link to the picture but i still dont know where it goes or what to do with it. Maybe i missed something on the shbox web site.

It connects to your RH O2 sensor in the exhaust pipe.

The factory Y-pipe had an O2 sensor a few inches down from the connection to the passenger side exhaust manifold. You have to take the O2 sensor out of the Y-pipe, and screw it into the bung on your new Y-pipe or the header collector (depending on whether you installed "shorties" or long tubes), just like you had to take the driver side sensor out of the base of the exhaust manifold, and relocate it to your headers collectors or the Y-pipe.

Looks sort of like this on my Formula with mid-length headers:
