I just finished installing the autometer(lightshow) a/f guage.
I dont think I am getting the reading right.

here what i did.

purple wire-connected to my white wire in the o2 sensor(black black green white)

red-power window

black-ground

I am i doing something wrong here?
would it be better if i connect the o2 reading in the ecu instead?

my car-obd2 accord 2002

 

bro you connect it to the actual o2 sensor white wire the whit one that is attatched to the actaul o2 sensor to get the acurate reading or else it wont work.

 

that's what i did, but it's something else.

thanks for reply it's all fixed now, haha

i found my other a/f guage i though it's lost long time ago.

now i have two a/f guage now..haha
