I took the advice here and got a Dolomite one from eBay. Problem - it came with a 6-pin plug and mine (86 Fiat +4) has a 5-pin socket. Swapped the 2 plugs but..... there's an extra wire, black, with no obvious place to go. It operates the wiper (fast and slow) but not the washer. Any ideas folks? Did some experiments with the black wire but no joy.
