Which wire do you tap into to get a correct reading for an air/fuel gauge? Kinda stuck on installing a A/F guage on a 2000 solara. Thanks yall
Im really stomped on this one.

you can tap it into the o2 sensor wire.

Thanks for your reply but which wire is that, there are 4 to choose from: 2 Black, 1 white, and 1 blue.

 

[atobe]

get a pen tester. 3 of the wires are for the o2 heater. if i had to pick i'd say the blue wire. cause there's 1 5v 2 ground and 1 signal wire

Ill try to tap into the blue wire tonight, Ill keep you posted. And thanks again for your reply.

actually the 2 black ones are ground
1 blue is the heater
1white is the sensor itself

 

[atobe]

opps i was wrong once again

 

[hnda8r]

So should I still go for the Blue wire?

 

[BustaRice]

which area of the car are you tapping the wires from? i need to tap an o2 sensor to my AFC but dunno where in the car to tap it to

 

[2wickedtoyz]

the white wire on the front of the engine is the one to tap for simplicity i tapped the one in the middle of my car which is alot harder to get to

Success!! Finally got the air/fuel gauge to work. I just tapped into the blue wire and turned on the car and waited for a couple minutes. I see no purpose for it really, but I got it working (w/ the help of some of you here). I dont see how its suppose to be accurate at all. All it does is go back and forth. Only when you go WOT, shows a steady reading, but other then that its just for show. (your right Yanks )
So people with a 2000 solara, you must spend a crap load of money to get an accurate reading.

Yup.

I always try to tell people that those a/f gauges are worthless, some ppl just don't listen.

Only way you'll get a true reading is with a wideband O2 (UEGO) setup.

woo hoooo i was right it was blue. yeah it is pretty useless it goes back and forth so many times when u drive. but it's fun to look at for awhile then u get tired of it

 

[hnda8r]

My buddys next step is to go wideband
For $400.00+ he better get the correct reading.
