Before answering this question, let's get our bearings:

Optionally, the YELLOW (Analog out 1) and/or BROWN (Analog out 2) can be connected to the analog inputs of other devices such as data loggers, gauges, etc. The BLACK wire, calibration wire, will not be used in conjunction with the XD-16 in this application and should be taped off and tucked away.

So we have two analog outputs, just as Justin mentioned. The instructions for datalogging with an XCal state that both analog outputs are to be wired to the XCal. So if one of these must be connected to the PURPLE signal wire for your A/F gauge, the question becomes which one? Let's lookup the difference between Output 1 (YELLOW) and Output 2 (BROWN):

According to the above spec, the YELLOW wire is the narrowband signal and the BROWN wire is the wideband signal. You'll want to wire the narrowband signal to the A/F gauge. Initially, the wideband signal will be used for datalogging. Later, the narrowband could be used instead for fine tuning. See the following illustration:
