I need to know what wires go to my aux on my PLX wideband coming from my stock ecu, my car suddenly dosnt run right and I dont understand why?

I am putting on my flame suit here, i have been running without a o2 sensor hooked up to my ecu for a week or so, I have a wideband to moniter afrs and suddenly my car runs so pig rich that it wont even idle without being floored

I have checked every possible connection to my engine for leaks of air/vac and nothing.....

ANYONE i need some help


I run on a 1994 Legacy EJ22 2.2L engine...
