Left over plug identification

[Richie-Van-GTi 70 2 Cars]

I have a few left over plugs after fitting a gti6, standard loom. Can anyone identify them.

3 pin white plug, attached on the same branch as the reverse switch, not TPS as that's already plugged in.

2 plugs near the throttle body but everything is plugged into throttle body.

Black 2-pin is unused and can be ignored.

 

Blue 2-pin is the PAS pressure sensor - unused if you don't have PAS fitted.

 

White 3-pin could be the VSS (vehicle speed sensor) if it's long enough to go down the back of the gearbox?

No vss is already plugged in. It's baffled me, could it be going to radiator or fans ?
