O2 sensor question.

[Logan76]

Mkay, I bought my CA swapped in already, but Ive done a good bit to clean her up and make her more suitable lately, she was in somewhat deploreable condition when I got her...when I took my O2 sensor housing off of my turbo, for the SR T25 swap, I realized he had the O2 sensor wired just taped up and went into the firewall to the dash, He told me he used to have a narrowband hooked up, but the O2 sensor wasnt hooked into the harness at all, and I cant find where it would've been attached at, and I assume my gas mileage is suffering from this, even though the car ran fine before I tore it down. just for the record I cant wire up a headunit, so I hope you guys can just point me towards a connector that it will connect to, I couldnt find one...

Any ideas?

its a 3 wire plug coming from the o2 sensor, and the harness. red=power, black=ground, white=signal
