what does the air fuel gage hook up to ? ( b series)

 

Power (something like a radio fuse), Ground, and the Green wire on your O2 Sensor.

 

o2 sensor,so u just splice in to it ? thanks man

 

The air fuel guage should have come with instructions.
The red wire is 12v signal
The black wire is a ground
The purple wire is your o2 source

If you have an obd2 vehicle I recommend you tap right into the white wire of your 02 sensor that runs into your exhaust manifold.

To be honest with you air fuel guages wont tell you shit. Why? Because your stock o2 sensor only reads a limited amount of air fuel ratio.

You need an expensive tool called a wide band oxygen sensor in order to get real air fuel mixture readings.

Good Luck.

 

yea i got it used ,no instructions thats why i posted this, i have an obd 1 computer, so its not worth installing ?

 

Go ahead and install it if you want to, but it wont do much but look cool.

 

ahhh thas shitty air fuel gage for sale $$$ hahahaha..

 

Splice the purple wire into the white wire coming out of the o2 sensor. I ran my 12v to the cigarette lighter, and ground to my alarm ground.

 

i hooked it up and it dont do shit , looks like knight rider on crack oh well ....
