02 sensor wire help please????
I've just fitted a AFR gauge to my car 93 wrx, it's an autogauge if it matters. I think i've wired it wrong though because only one LED lights up on lean and doesn't move at all. When the car is idleing and i turn the lights on another LED will light up???
Which plug to the ecu has the 02 sensor wire in it, want to wire it here really as i read if you do it straight off the lamba sensor it won't read as accurate????
Do these need a very good earth ? Because i've just crossed the earth wire with the same earth for my boost gauge????
