where in the heck should I hook my a/f gauge to

[wornoutsupra]

So I am not getting any ready from my a/f gauge I tapped it into the wire I thought was right, which was the oxygen wire i believe it was a white wire on one of the big plugs from the ecu. Now is that the right one to hook my a/f gauge to or is there another place that would be better?

I'm assuming it's a narrowband? Or are you trying to immulate the stock ecu?

 

[wornoutsupra]

its not a wide band or anything its just a regular a/f gauge nothing special and what do you mean by trying to immulate the stock ecu?

 

[Albert]

Oh okay. I'd assume just T it into the oem o2 sensor wire. You'll have a ground a positive and a input I'm assuming for the gauge. Not 100% I've never messed with a narrowband gauge.

And the immulation is if you had a wideband like the Lc-1. You can get rid of the stock o2 sensor and send the output to the ecu and getting readings off the wideband.

"emulate"

ha ok cool yea i have the ground and the power hooked up and I know they are good because the gauge lights up and all so the best spot is just tie into the o2 sensor and that would be my best spot then correct?
