As long as you disconnect the +ve feed then it shouldn't dribble.
I had trouble with mine where I fitted a 2nd hand bumper with headlamp washers, as previous bumper didn't have washers, fitted the bigger 5L washer bottle, tested both motor pumps, both worked, but voltage wasn't getting to headlamp washer motor. The relay that was fitted was a non-Alfa relay and it was bust... fitted 2nd hand Alfa relay and headlamp washer worked, i think, and then when I turned the engine off with the key out, the side lights were permanently on. I took the relay out in the end.
