wind shield Washer tank power hook ups ?

[Paul W]

I replaced the rubber gaskets on my windshield washer tank on a 87 300d. It took a while to get the new gaskets and now I can not remember where the wires go. One line has two wires and one has three. Does the three wire one go to the head light washer, or the windshield? I was able to hook up the low level plug because it was a different shape.
