Sometimes the relationship of the TT to the Gulf is quite nice. For example, if one notes that the rain sensor is almost plug and play matches. One need only the sensor itself and the relay WiWa the Golf IV (No. 192). Although this sensor to have the golf only with the auto-dimming interior mirror, the whole thing can be achieved even without the mirror. The two operate completely independently of each other ie.

List of materials:
- Rain Sensor 1J0 955 559
- Adhesive pad for sensor 1J0 955 609
- WiWa relay 1J0 955 531 1J0 955 531 A or
- 1x connector 000 979 135 E

Normally, the sensor in the base of the mirror is placed (golf) or has an extra housing (Beetle). One can very well do without, but because on it, which makes the required area smaller. I stuck it right next to the mirror, because it is also important that he is not disturbed by the wedge and still sits within the wiper field. The three cables I have hidden in a black heat shrink tubing.

The electrical part is totally easy. The brown wire of the sensor must be connected to ground, the same can be done on the roof top. The other two cables must be extended down to the relay box under the steering wheel. Here we investigate the old WiWa relay with the part number 8N0 955 531 B (brown shell) and clipped the front of the 4 relay support brackets to the rear (green markings in the picture). Then, the purple plug fuse on the back slide to the side so that new connector can be pressed. Pin 10 is now on the black wire connected with one of the plug and the green wire on pin 14 of the sensor. Then lock into place, clip the relay holder back and plug in the new relay No. 192nd

That's it for now. If you pour now in the position of the wiper interval with a watering can on the sensor, it automatically wipes. At the interval wheel can adjust the sensitivity in all lever positions other one has the normal velocities, as usual.
