ok so i have been piece'n together a turbo kit for my DOHC 99 r/t neon.. i got an srt boost guage,turbo,intercooler,exhaust,all vac and oil lines,air/fuel ratio guage,blow off vaulve,and boost controller.. only problem is, is that i went to hook up the air/fuel guage and i dunno what wire on my oxygen sensor is the "signal" wire. also i am guessin i should hook it up to the lower one rather than the upper one? i didnt look at the bottm one yet but on the top sensor there are 2 black wires,1 white one, and 1 grey one.. please help

 

Get a haynes manual, they have wiring diagrams in the back. If you don't get a reply by the time I get home, I'll look it up for ya. I may not be home for a couple hours though.

 

thats weird, my 96 has 2 white, 1 grey, and 1 black. (upper, on header)

 

you are going to want to run the a/f gauge off the top O2 sensor... and I would get rid of that narrow band and pony up the cash for a wide band... your A/F ratio is the most important part of having a happy boosted vehicle

 

ok.. honestly man, i have no idea what your talkin about.. lol i mean i've seen AEM wide bands before.. this is one big learning experience for me. like i know how to wrench, i grew up around cars but the thing is, is that my whole family is into the old muscle car stuff so this ismy first time ever messin with turbos.. can ya please explain? haha sorry

 

oh and i got it mixed up, my car has 2 white 1 grey and 1 black..

 

Suposed to Have only 1 wire to the O2 Sensor?!?!

 

you dont know what your talking about. The ones on neons have four wirestwo are for power the other two are for the heating element

ok the difference between wide band and the stock narrow band is that that narrow band basicly only tells the pcm if the motor is running lean, rich or stotch... doesent really tell how much and if it does its in big steps... and tends to sweep from stotch to rich or stotch to lean back and forth back and forth...

Wide band will give you a very accurate reading with very very small steps Giving you a exact reading... and it doesent sweep it gives you a real time reading... some will be a gauge type with a needle some are digital and give you an acuall read out in numbers... some have both...

But the narrow band is not enuf to give you a good reading to properly tune a turbo setup...

most people leave the two stock o2 sensors and have a bung welded into the header for the wideband and just run the wideband asa standalone... meaning it wont be giving the pcm any info just you... it lets the stock o2 sensors do what they were ment to do while giving you the info you need...

hell some like hte intovative can hook up to a laptop for data-logging...

 

alright i def understand better now, thanks a lot. def very helpfull
