i cant get them to work, i thought it was a loose terminal on the earth so i made a new connection but they worker itermittently for a while and then stopped. when i put a meter on the terminals of the multiplug near the washer bottle i get 12v on either side on the pins, i thought one should be 0v. there are 2 outlets on the pump to feed the water, one for the front one for the rear, are they marked which is for each one ???, this is beginning to p**s me off as i want to take it for its mot as i have been restoring it for 2.5 years and want to get it back on the road
