Hi from Aussie TomF.
Saw your post on intermittent wipers awhile back, and see you had the same issue as I do, in that the Int relay is NOT a direct plug in replacement for the original. But you managed to get around it! Well done.
Can you advise the wiring involved please? I have the stalk fitted in my 2003 Mk4 Convertible but as the relay did not plug in, I was stymied. I can follow your pic and the wiring for new relay is pin for pin connection (although the pin ID on both relays differs - new =53e,31b,15, and old =30,87a,87). Then 53c,31, and 'I' connects to the extra wiring from the stalk, but which connections?? Looks like 86 in the base is not used, maybe 85 as well.
I also used a Dremmel to hack out the plastic grille in the fuse box base and get to that annoying buzzer. I have a light cable run to where it connected and intend to put a more pleasant sounding 'chime' with timer in it's place. It's so peaceful when working on the car now!
Thanks - Roy
