I dont want to run a cable from my old o2 sensor into my cabin, i'd like to just use the wires that are allready run to my ecu. I do not see an o2 on that pinout. Can anyone help?

I drive a 99 Civic Si. Thanks in advance!


Also, i'm wiring up my Zeitronix Wideband, it has a wiring setup like so


red switched power (ex. ignition)
white wideband analog out (wont be using this)
Green RPM input (0-5v square from tach)
Orange Boost sensor in
Yellow Boost sensor +5v pwr.
Black Power ground
Brown Sensor ground
Purple 02 sim (to ecu)
Grey TPS sensor
Brown Sensor ground (again)
Blue User input (0-5v)


Help me, i dont know how to wire about half of this. Do i connect the red wire to an acc pin on the ecu? please help.

Maybe i can get some help here? Thanks in advance!
