If it has auto wipers the sensor is located behind the rear view mirror, easy to see from outside as there a black 'lump' around it on the screen.
On the ph3's the wiper relays are purple but but may not be in ph2s!
Edit - The only blue relay I've seen on a 306 is for the rear wiper and that's not near the fuseboard!
