Passat B5 2005 last of old shape - Installing rear parking sensors

Hi
need to install Maplin wireless rear parking sensors
once 4 holes are drilled in in rear black bumper - how do you get the wires into the boot area ?
the rear transmitter is wireless to the dashboard monitor - so no problem there
kind Regards

Easiest way is via rear air vent, once the bumper is off, you should be able to see it on the offside.

thanks for info - but is there any way to get the 4 sensor wires into the boot space without taking the bumper off
and without any further drilling holes ( if a further hole or holes need drilling please advise the best position )

Taking the bumper off isn't difficult, it's just a case of going round and removing the fixings, then it slides off easily.

Found out a so easy solution !
in the spare wheel well at 6 oclock position there is a large 30mm rubber grommet
Make hole and wires pass through easily !
