No 1 sensor? M50 engines only have one sensor. (every one ive seen has anyway)
M52 engines have two, one in each manifold
Depends which part of the wiring you are looking at also as the colours usually change through connectors

What sensor though mate? Standard M50 sensor, the black is the signal wire and the two white are for the heater, grey is earth I think
M52 sensors are down by the frontpipe joints
