Air/Fuel meter

[Reason]

I hooked up my autometer A/f meter and it seems to work. I just want to double check to see if I wired it up correctly. I tapped into the signal wire on the second cat. I assume it hooks up to the second cat and not the first am I wrong? I know Subarus run lean, but according to this meter its wicked lean lol

lol you have a gauge to see the efficancy of you cat. :lol: it hooks up to the front O2

[Reason]

What wire is the signal on the front o2?

Only if you use a piggyback of some sort or your ECU is supported by rom raider/openecu.

What wire is the signal on the front o2?
it should be the same color wire as the rear O2. i think its the white w/ blue stripe (for the signal). i think yellow is for the heater and the black is for the heater ground.

Thank's, I'll mess around with this later.

Are you getting the signal at the ECU or outside the car? What car is this on?

Using an air fuel reader on a narrow band sensor really does not work too well. I had one on the stock EGO for a while and would compare it to my wide band. I could be at 15 AFR and the narrow band would show that I was really lean.

It's connected to the front 02 sensor (outside of car) It's more just playing around. I don't plan on keeping the gauges for long.
