airfuel gauge help!!!

What color is the wire I tap into at the o2 sensor for the afr gauge? asap help please!

From what I understand on the other forum, you'll want to install a 2nd WB O2, do not tap into the factory O2 voltage wire.
However if you want to go ahead the wire should be in this diagram in the very bottom left, one of the 2 pins to the front heated O2 sensor

Your assuming I no how to read this...I really dont.....I relize that a narrow band is not as accurate and you should have a wideband but this gauge is for looks. Please help me decipher this..I want to use the front o2 sensor(in the engine compartment).

if the gauge is for looks why not just get a sticker that looks like a gauge.. or don't even tap into the oxygen sensor at all?

Widebands aren't all that expensive

Because and who cares can you help?

The factory #1 O2 sensor is a wideband O2, it's $400 or so, if you fubar it you won't be happy.
Buy the ATP turbo downpipe with the 3rd O2 sensor bung and buy a cheapie WBO2 to put in there would be my opinion.

I do not know which of the wires of the 7 listed is for the A/F readings. The only way I would know is to have my scanning software on and reading the front O2 voltage and hit the wires with my volt meter to see which one matches. However I was told that this process can hurt the O2 sensor (I don't really believe it but that's what I was told) so I'm not gonna try it as I don't need to.
Sorry, this is all the info I got.

ok,...thanks anyway

Well if the first sensor is a wideband, definitely don't want to tap into that for your non wideband gauge.. it won't be able to understand it.

 

[ssinstaller]

the stock wideband sensor uses 4 different wires running to the wideband controller to generate the lambda readings. If you try to tap into any on eof them you will probably damage the wideband controller, which will be a very expensicve mistake if it's part of the ECM..
