AEM UEGO Gauge Help

[Icarus]

I recently bought a AEM UEGO gauge-type controller on Craigslist for $20. It's only the gauge and the previous owner complained that the reading were off by few points (AFR not lambda). She decided to get rid rather than figure it out. I figured for that much I could try to make it work if not, it was only $20. The only parts that are missing are the plug and the AEM style Bosch LSU. Still I figure I could have a decent wideband for under $100 if it works.

So here's my idea. Set up a bench test before wasting money on the sensor or any other parts.

1. Get a 12v lamp battery to simulate battery power.

2. Put an inline resistor on the wires to get a fixed value and fixed reading for the on 0-5v circuit.

The questions I have are:

1. Where do I find a replacement D type connector without buying a replacement harness?

2. What do the colored wires represent on the sensor wiring harness? (2 for 0-5v? sensor ground? power for something? 2 for heater?)

I've gone to the AEM forum and that's next to useless, so any help would be appreciated.

Been there but if you have a link to what I'm looking for please post. Thanks

This took 5 minutes to find. Should answer your #2 question. I think you can get the clip at any electronics store.

I've already read through that a few times. It does have the colors for the gauge harness, but not the sensor harness. If there are any obvious sources of information on the internet regarding this gauge, I've probably read them. I am hoping that there is someone that has some familiarity with this gauge and/or sensor.

I've looked at bunch of online electronic places that sell automotive connectors and pigtails, no luck. Same with Radio Shack's online store. The sales people at Radio Shack are pretty useless as well. Every time I go in there and ask questions I get the dear-in-the-headlights look. According to this link Ballenger Motorsports - High Performance Electronics, the sensor is supposed to be a GM replacement for some vehicle, but I can't figure what on GM parts finder. Maybe somebody has an idea.

Thanks for trying to help though.

I think I may have to just buy a sensor. From what I gather the outputs from the sensor are interpreted by the controller then displayed on the gauge and converted to 0-5v. I'm thinking about getting a the Innovate stye because I can find the part numbers for everything on the JAW wideband instructions. I will post back with results to see if any of this worked for the next person that needs this info. It could still be a bad gauge in which case I will have an extra sensor for the LC-1 I wanted to get eventually anyways
