Unknown connector and GPS tracker

[03gto]

Hi all
Have found a 6 way connector behind the drivers RHS kick panel in the VY GTO that I want to use to power a GPS tracker.
It has 5 wires in it.Two thick wires, black and green. Three thinner wires Yellow, Pink and Orange/Black.
The orange is from battery, Pink is on with ignition.
Haven't been able to check the others. Does anyone has any idea what it is for?

The GPS tracking device and also needs to use a speed signal so that it can shut the car down below 20KM/h.
Anyone know how to do this or installed one before.

Any help appreciated
Thanks
