ok so i noticed im not exactly getting the best gas mileage, and my car idles at about 13-14 on the wideband, i unplugged the O2 to see if it would effect anything, plugged it in, still continued to idle in the 13's

i have searched, i can't find a straight forward answer

i think i may have a blacktop wiring harness which is for the FAT o2 sensor, and i have a skinny o2, i heard the wiring is pinned out differently..

on the the sensor side there is a white, black and red wire.

-white is going to the black wire on the harness
-red is going to brown wire on harness
-black is going to what i believe is the white signal wire on the harness

everything check out?

i tested to see if any of the wires were getting power, and the red wire on the o2 is hot
