Mark,
The AEM gauge you bought 30-5130 does not have the ability to simulate a Narrow Band Sensor. That particular gauge does have a white output but it is not configurable, it's output is 0-5vdc and is NOT able to simulate the 0-1vdc narrow band signal. This gauge also uses the older LSU 4.2 sensor not the LSU 4.9. It's a decent gauge but the other AEM 30-4110 is the more modern slightly better gauge.
The AEM 30-4110 has a programmable white wire output that CAN be set to mimic a narrow band 0-1vdc output. This gauge also uses the most modern LSU 4.9 sensor. It's simply the very latest technology gauge from AEM but the face is digital (not analog) I wish they made this same gauge in analog.
Bottom line: the AEM 30-5130 is a decent gauge but CAN NOT be wired to the DME, do not bother trying to wire it up as it will only make your DME think the motor is rich at all times and the DME will get confused and lean the mixture. Again, DO NOT tie that white wire to the original O2 harness! If you send a voltage above 0.7vdc back to the DME it will tell the DME motor is RICH!
I did not realize what AEM you bought, most folks use the other 30-4110 unit.

Should I be taking the white wire back to the old O2 sensor green as mentioned above (is that the Lambda + input)? If yes then what about the brown wire? The instructions say it must be used if the white is used. Ideally this brown would be connected to the Lambda - input if there is one or to a sensor ground if no - input or finally to a chassis ground if none of the other two exist. Who can help answer my concerns?
