Easiest place to connect to O2 Sensor for A/F Gauge?

[irn__man]

Where is the easiest place to connect to the O2 Sensor for a Air/Fuel Ratio Meter (Autometer)? I looked at the VFAQ, but the link to the wiring diagram no longer works. Also my car is a 99 GSX, and my O2 sensor is 4-wire. Off hand which wire do I connect to? Or is their an easier place in the cockpit to hook-up to the O2 sensor output? Maybe somewhere close to the computer.

thanks

there is a wire comming from the ECU that is the best and most accurate! and you dont have to route any wires into the engine bay alot cleaner. use this http://www.vfaq.com/proj-pics/ECU/ecu-harness-2G.gif
depending on what kinda ECU you have, vertical or horizontal. Make sure you get the right wire the first time I tried it I connected to the 02 sensor heater dosnt work to well! =)

twitch,

would you happen to know what the number of terminal is on the ECU, that the O2 reading is going to?

thanks

Thats for the autotimer, but it uses the O2 wire, and it has a diagram of the wires coming off the ecu. Hope that helps you out.

I am having the same problem here too,i got my boost aguge all connected up today and have all the wires connected for the A/F gauge but am wondering also where do i splice into to hook up the O2 housing signal wire?

Check this link out, I found it to have better pictures and a little more info.
