Wiper relay upgrade

As standard the Defender has 3 speed settings for the front window wipers:

1. Continuous Slow
2. Continuous Fast
3. Intermittent (every 5 seconds)

In addition the wash wipe function wipes three times for every button press.

In light rain or road spray the intermittent wipe is often too slow and the Continuous slow setting can be too fast. To fix this, the standard (Red) wiper relay has been replaced with one from a Skoda (Black). It is very common to use  a VW relay, but the Skoda variant does pretty much the same job and is easier to obtain since it is scarcely mentioned on guides.

The photos below show the two relays and their position in the fuse box.

    

As a result the intermittent wipe time can now be programmed by turning the intermittent wipe on and then off after the length of time you want the wipe cycle to be. When you turn the intermittent wipe on again, it will assume the cycle time you set. I have tested settings from 1 second up to around 10 seconds.

In addition, the new relay also reduces the number of wipes from 3 to 2 when activating the wash/wipe for a short burst, but maintains the 3 wipe cycles when activated for a long burst.
