The older Alfa Romeos did not have an
intermittent wiper, which I find very frustrating. Here's a
clue how to solve that problem. Here we go.
The relay comes from a Volvo 850
model, in production for many years. Other Volvos had the very
same relay. The realy to the right, the black one is almost
the same, but from a VW Golf Mk2 and 3, part number 3B0955531.
Go to the scrap yard and browse or why
not to the authorized dealer for the models.
Connect the wires like this. Oh, the
wires are from a 105 series Duetto. Easy to install, relays
are at the junk yard. Place the relay anywhere you want,
behind and under the dash. Both relays have the same basic
wiring and connections. Good luck!

- S to the wipers
- 31 negative ground
- 31b from the wiper toggle, for full wiping
- 86 none, it is for the flushing pump
- Then finally, the very small connector to the right of
S, that's where the wire from the intermittent should be
Now, when the toggle is in the middle
position, the wipers will run intermittent. At the down
position they will run at full speed. Top position means
the toggles and switches for your Alfa
