Hope someone can help me out. I bought a used AEM UEGO Wideband Gauge with sensor. It's the gauge with the built in controller (gauge w/ harness and sensor). I did not get any documentation. Coming from the gauge, there is one harness connection to the wideband sensor and then there's another with four wires that get tapped into something. What do the four wires tap into? I assume one is power and another is ground, what are the other two? The color of the wires are Red, Black, White and Blue.

Thanks for any help. Would anyone have a PDF of the instructions?

 

Blue wire is for logging, white is the output of the WB. If you're not using logging software, or letting an EMS do it you won't use the blue wire. I'm not sure how to run it with the stock computer. You will probably send the white to one of the two o2 inputs, probably 1, and disconnect the stock one. Not sure so check first! They're picky about how they're grounded too so make sure you do it right!

 

I couldn't find PDF downloads, but this might be a good place to dig deeper. I'm sure someone can help you out.

I have the same gauge running with my aem ems. If are not running an ems or data logging all you do it wire the red to a 12v switchable power source and the black wire to a chassis ground. The blue and white are for data logging and wb output. I do have all the instructions if you want me to scan them and send them to you.

 

Not wanting to hijack - had a quick question. Can you still datalog AFR with this unit?

 

Thanks guys for all the info Flynavy and Strongbear. I don't have EMS so I guess will only need the power (red) and ground (black). So if I understand everything, the blue and white are outputs for logging. Down the road, I will interface the wideband with the Xede for logging purposes when I have version 3 of the Xede firmware.

Strongbear... it would be great if you can scan the instructions for me. Can you post them here?

 

Here is the page with the wiring diagram. I hope it helps.

 

That helps very much. Thahnks Strongbear!

 

No problem, glad I could help.
