The wires are for external logging capabilities. For example, if you had an AEM FIC the the White wire would to the the FIC and the brown would be grounded. I don't fuilly understand the season for two wires though.
From the manual if you don't already have it.
WHITE – The WHITE wire should be connected to the Lambda + input on the
EMS or the analog + input on a similar device.
BROWN – The BROWN wire should be connected to the Lambda – input or the
analog – input. If the EMS or similar device does not have a – input, the BROWN wire
should be connected to a sensor ground. If no sensor ground is available, the BROWN
wire should be connected to a power ground. Note: The BROWN wire must be
connected in order to get correct readings from the analog output.
