Wiper delay mods for W124's?

[nehuge]

Hi guys, saw other forums out and about but no one answers since the discussions are super old.

I heard that you can use a Volkswagen Relay (called 99 relay) to set a programmable delay for the wipers rather than the 6 second one that comes from the factory. I live in Oregon, so the mist and spit can be random. I know there is a N10 relay by the fuse box that controls the rear defogger, hazards, and wipers. They were talking about using a 99 relay that you can set the amount of delay but switching the wiper stalk to position 1, and then off really fast, then waiting whatever seconds you want, and setting stalk back to position 1 and it'll repeat that delay.


I have some of these so-called 99 relays but not sure how to hook them up as the N10 relays are pins, and the 99 relays are spades.


Anybody have any ideas? How would this 99 relay go between the N10 and the car? How does this work if the N10 pins plug into the car directly?
