Logging your wideband output with FastWorks

The majority of wideband gauges have an analog output. This output can be wired to your OBD2 plug so you can log the vehicle's air/fuel ratio with all the other engine parameters. You will need to consult the owner's manual for your gauge to determine which wire gives the 0-5v output. You need what's called a linear output instead of a narrowband simulation. This wire needs to be connected to Pin 8 on the OBD2 connector. The female pins will depend on the vehicle as there are 4-5 different manufacturers of OBD2 female plugs found in vehicles. I recommend visiting your local scrapyard to harvest a plug so you can get the correct female pins. If you know who makes the housing you can generally order the pins from an electronics supply house such as DigiKey.

This is a Bosch connector housing. It is used on the majority of european cars as well as the Lotus.

I've added the AEM directions for those who have not been able to find their documentation for an AEM UEGO gauge. Please note the analog ground (brown) must be connected and the white wire 0-5v output goes to the obd2 plug.

I have tested and found that the bosch female terminal will go into the mitsubishi plug.

Glowshift widebands, I don't recommend them because of accuracy issues but here are the instructions:

Should be the brown 0-5v wire.
