They're the connections for the 2 sensors under the car. They are colour coded as you suspect. (Mine are crossed over as I have equal length front pipes fitted.)

The rear bank pre-cat sensor connection is in the black box on top of the thermostat housing and the front bank sensor connection is down by the air con compressor.
