This kit is nice and easy to install, just plugging in in place of your standard intermittent wiper relay.
There are two possible ways of fitting it. One would be to apply the sensor to the windscreen (following Hella's instructions), and then run the wire to the left of the windscreen in preparation for installing the relay. The other which was the one I chose was to install the relay first, and then fit the sensor.
The relay you are replacing is located uderneath the dash, and is accessible by removing the shelf from below the glovebox. The shelf is held in place by 5 screws, 3 of which are easily accessible, the other two are hidden by the centre console.
After removing the shelf and centre console, you can now get access to the underside of the dash. This is where the torch comes in. The relay you want is hidden behind some wiring, but is clearly distinguishable, as it is the only one displaying any text on it (far right hand side).
(This is what the relay should look like.)
Now placing the Hella relay unit in the now vacant slot (text facing down, as standard one), you will need to route the wire to the sensor unit. I found that you can tuck the wire between the dash, and the shell, and then run the wire up to the pillar for the windscreen.
(Note there is a slight recess that will allow you to run the thick wire from under the dash.)
After running the wire up the dash board, I found the next best way to go was to route the wire between the dash and where the speaker grille sits.
If you then curve the wire back on itself, you can hide the wire under the seal for the windscreen on the left hand pillar when you are happy with the positioning of the sensor.

Following the seal for the windscreen, you can route the wire to behind the rear view mirror, and connect this up to your sensor unit. When you are happy with everything, the wire can be tucked under the seal, and everything put back.
The next step will be to set the sensor up which is detailed in the instructions for the kit.
