85 oxygen sensor installation

Hey,
I have an 85 rx-7 (not se), and I don't know where to connect the wire from the oxygen sensor to. There's an oxygen sensor installed, but it looks like someone cut the wire that leads to wherever it's supposed to be connected to. I just need to know where that wire is supposed to go to.

It goes to a non-mazda gauge.
