There are four such connectors, as shown in this photo. They are generally colour-coded but there is a duplication on the black ones. It is physically possible cross-connect some of them if you are totally colour blind. This post is intended to help prevent that.
Starting at the G42 Intake Air Sensor and going anti-clockwise, the connector and wire colours are as follows:
The brown G42 IAT connector:
The black ISV connector:
The blue N80 Evaporative Emission Frequency Valve connector
The black Auxiliary After-run pump connector (two pin, three wires so not to be confused with the N71 ISV connector):
These photos will be added to their respective posts and linked back to this post.
