Connector mystery

Hello,
wondering if anyone can shine some light onto why the below two connectors are on the car and what they are for.  neither are connected to anything obvious and the car runs happily…?

This one fed by the green wire is on the throttle body/inle manifoldt, just above the breather pipes


The second is down in the free space above the gearbox and is just resting on top.  Some wires aren't even connected?



The car does have 3 VDO gauges on the centre console however none of them work (all the sensors are VAG sensors and drive the original instrument cluster gauges)

Cheers
Dave
 

The first one should have a green connector which comes from near bulk head and taped into to expansion tank wiring loom

The other looks as if it is the reverse light switch connector IIRC.  If they replaced the tranny and it has a different switch they may have cut and spliced a new one on the tranny with wires from the old switch?

pic1 is the throttle switch for the cold throttle enrichment system, its only used on late KJet cabrio and scirocco, the tintop gti didnt have it. if you dont ahve the wirign for it then its probably had a later engien swap into early car.

2nd is the early MFA reverse switch, for the cluster with the MPG needle and shift light. again if its had a later box put in they only have a 2 pin reverse switch, which is what the 2 cut wires on the plug are for.

Thank you for the replies everyone!
It is a DX engine but not the original so may be an early mk2 8v engine as you say. 
The reverse switch on the gearbox is only two wires, so same again there!
