I recently bought a auto meter a/f meter and I cant find a good place to tap into the o2 signal wire. I have a 98 integra LS. I was think of taping into the o2 sensor on the cat but wires are to far away! Anyone know a good spot?

 

i did both of my A/F ratio guages to the white wire on the o2 sensor,..you can always go to your ECU but i forget what wire you have to tap into for the ECU

 

I am pretty sure that it is pin D14. But I couldnt find the wire under the dash.

 

where did you connect the red wire to meet the ingition switch?

 

u should really get a haynes manual with the wiring diagram with the different color wires so u'll know what to tap into, on my crx the ignition wire u would want to tap in under the dash is black with a yellow stripe, but id check with someone who has the wiring diagrams for ur car to make sure, it might have changed in 10 years.

 

yah on a crx it'd be pin c16 so pick up a haynes or helms at ur local autozone and get a book for ur particular model, otherwise u can just run a wire from the o2 sensor and wire it all the way back thru ur firewall if u want to just have a long wire.

 

I went and bought a chiltons book w/wiring diagram. I figure that I am just going to connect all the wires to the harness behind the stereo, ground, switched power, and dash lights. Then run the signal wire to the o2 sensor on the cat.
