02 sensor replacement.... ^w-t-f mate?

[.RJ]

So the miata had been a bit down on fuel mileage, with a CEL for a little while, with a bad o2 sensor listed as one of the triggers for the light. I figured, its got to be the o2 sensor, after I fixed an exhaust leak after the pre-cat (new gasket).

I get a new OEM sensor from Felton today, so I pull the old one off.... sho' nuff its a 'universal' type that you wire into the factory harness. Those things never work worth a shit.... but I was curious how this guy "wired" it in.....

Pics speak for themselves on this one:
