Bought a Rclick kit and installed it today...took 5 minutes and works faultless. Didn't bother with the plug n play cable, it's so easy to do its really not worth the fifteen quid.
If installing in the boot by the pump do as follows.
White from Rclick loom to grey on pump
White/ black to green on pump.
Black to brown on pump which is earthed on a stud on the rear quarter.
Yellow, yellow black and red to the red/ white on pump which is the 12v supply
One brown to black/green on drivers side light cluster
Second brown to black/white on passenger side cluster.
This was all done with the supplied quick crimp thingys. Plugged in to the box and worked perfectly!
