I have searched these forums forever and cannot find what i'm looking for. One time i came accross what i needed then fell asleep at 5am drunk as hell.

I have a aem uego wideband. as you can see i have an 02' k20a2 motor. I need to run my o2. I have the wires wired up everything is ready to be put together. Also i have no clue which wires to splice into with the o2 sensor. How can i use the bosch replacement 02 that comes with the aem wideband and use it for the primary o2?
When i called AEM they would not give me the pins for the bosch replacement nor tell me what they were used for they did say that the 4pin that the aem wideband comes with will work with the ecu readings. I CALL BULLSHIT.

cliff notes:
How can i use my uego wideband for a primary o2 sensor for my k20a2. PLEASE HELP!!!

There are 4 wires. Red, White, Black & Blue.. You wont need the Blue one....

Red goes to a 12v source
Black is Ground
White goes to the O2 Sensor signal wire. ECU pin A6(Red)

What instructions are those for? Which set of wires? I'm guessing the 4pin for the uego gauge.
Those instructions are for the wiring harness that comes with the uego gauge That's all you wire into your cars harness..... The gauge itself has pins on the back where plugs go onto.

I have no o2. I need to get the o2 that the gauge came with wired into my car so the ecu will read my o2 sensor. How can i make this happen?

The O2 that the Gauge comes with is different than your factory O2 sensor. I dont think it will read it. I still dont understand why you want your ECU to read it.
