AEM UEGO Serial Cable Instructions
There is a blue wire that is coming out of the back of the gauge from what I remember (did this months ago so a bit hazy). That you solder into pin 2 (crimping will work temporarily ask how I know). The ground pin technically doesn't need to be connected for this to work (don't ask how I know that either 
).
).
I also have the UEGO gauge but don't have the blue wire connected to anything as of now. I have the tactrix cable. Am I soddering in the blue wire into the connector that is under the steering wheel? Very confused about this, if anyone has a picture of the finished product that would be helpful to all I'm sure. Also, this should be a sticky

Solder a 3ft lead to the blue wire coming off the gauge, and solder the end of the wire into the #2 hole on the D-Sub connector. You will need to solder a ground into the D-Sub connector as well. It gets soldered into the #5 hole. With a serial to usb cable (Buy the $30 Dynex one from Best Buy) you will be able to hook it up to your laptop and log the AFR using EvoScan.
I will take pics of the connections tonight so it's alot easier for people to understand.
Sorry for the crappy cell phone pics.
OK, I took some pics real quick this morning before I jumped in the commuter car for work.
This is the D-Sub connector wired. I used blue and black wire to keep the continuity with the blue wire coming from the AEM gauge itself and a black wire almost always meaning a ground.
Here is the back of the connector where the wires actually feed in. The smartest thing to do, like others have said, is to make 2, three foot wires so that the connector can hide behind your ash tray, and then you can take it out when you're ready to log. Like I said before I used a blue wire and a black wire. The blue wire runs from the D-Sub on the back of the connector to the blue wire on the back of the gauge. The black wire runs to a ground plain and simple. To install the gauge and be able to log, you will have to run 2 grounds, 1 from the gauge and 1 from the D-Sub. I crimped and soldered the ground wire from the gauge and the ground wire from the D-Sub into this:
I then used a bolt that is on the inside of the driver's side fender very near the fuse box and kick panel as a ground. That bolt already has numerous grounds on it, so be careful if you are taking it all the way out in order to use it as a ground. (Sorry I don't have pics of the ground I used)
This is a pic of the Dynex serial to USB connector connected to the D-Sub connector all ready to log:
Hopefully seeing pics of the completed D-Sub will help people out. I know seeing actual completed products makes it alot easier to make. Making the connector is painfully easy, but sometimes it's tough to understand without actually seeing it. If anyone has any questions, don't hesitate to PM me. I'm not an electrical expert at all, but I can help you install this gauge and be able to log.
