I think they are just splices. what is wrong with the wiring on the one you have now? also if i can find it, i know i took it off, but if i can find it i have the wiper motor that i took off my 73 duster you can have.
As pointed out with arrows in the photo, there are a lot of spots where the wires have no insulation. Nothing some time with a soldering iron ans shrink tubing and a a heat gun wont fix..Thanks for the offer on yours!
