O2 Sensor

[ledesma54]

Okay iam trying to install a air/fuel gauge in the 04 gto and i was wondering what is the color off the wire that the sensor hooks up to, its on the driver side if that makes a difference.

It does matter, I wanna say the white ones are your heat and the black and blue are the signals... who is the wideband made by... you should be able to look up the install docs on thier website.

if your putting in the wide band for your a/f gauge your best bet woul be to drill a new hole in your exhaust and weld in a bung, then run the wideband in the new hole, leave your stock o2s where they are and not tap into your front o2 wires. just run new wires to the wideband..... might save yourself a lot of headaches later

blue worked on my 99 and my friends 00. black worked on my other friends' 98 and 01.

I think the 2 whites are heater wires, the black is power or signal, and the blue is whatever the black isn't. (Different on differenent cars) I would try blue first.
