ok, i am chep and i did not buy a wideband air/fuel ratio gauge...yet. so i got the narrow. so, my question is which wire is the oxygen snsor signal wire? on mine(and probably yours as well) i have a blue wire, two white wires and a black. my logical guess is the black is the heater ground and the blue is the heater power wire(12V) so im wondering....this is stupid logical guesing....which white wire is the high O2 sensor wire and which is the low, or ground....or how can i determine all this wires i guess?.....i hope this wasnt to confusing....thanks

Before I tell you may I attempt to change your mind? People dont buy the wideband because it costs $250+, they pay to $250+ for what it can do for you. A narrowband gauge on this car is worthless, you just get a light show, if it has lights. If simpy for show tap into the blue wire, that is the signal wire, black is ground, white is heater power, the other is either another heater power or it is the heater ground, not sure. You will not get an accurate reading with that regardless of what you do.

A wideband will give you the exact A/F ratio in a digital number to the tenth (14.6,14.3,13.0). Save money, get the real deal, the end.

not only does it just give a light show, it also messes up your 02 sensor.

Probably because most people install them wrong. You arent supposed to tap into the wire coming out of the oxygen sensor. You tap into the o2 sensor wire just before it goes into the ecu.

ya, i know im suppose to attach i to the wire that comes out of the ecu, but that is behinde my damn dash, and i know that will be a pain cause a buddy of mine had to prety much pull out the whole center part where the comp is located.
