Paul is right on the spade size for the lucas wiper motor, it's 3/16". I bought the insulated ones but then pulled off the insulation in favor of a double shrink wrap. I crimped on the connectors with both 1/8" and 3/16" shrink wrap on the wire. Pushed up the 1/8" and heated it then a longer piece of 3/16" over that. I gave each connector a squeeze with the pliers just to make them nice and tight. Used needle nose pliers to insert them into the socket then for good measure covered the whole set of wires with 1/2" shrink wrap. Used a 3/8" grommet through the fire wall for protection from shorting. I'll bet my connector will last longer and be more reliable than anything lucas makes. Here's a picture. Regards, Rick
