The LAMBDA is a TITANIA SENSOR, wire colours as follows,
RED = HEATER +/ref (in) for signal
BLACK = SIGNAL(output to ecu)
WHITE = HEATER -

Car Loom,
BROWN = -
The other two I am not sure of but just probe with a digi metre, and one will be a refference signal output from the ecu, most likely the black/white as, anything black on fords is normally switched live, so this goes to the RED of the sensor, the remaining wire GREEN/BLACK is the signal return, so goes to the BLACK of the sensor.
You will only have one output from ecu so probing will find this.
