There are two four wire conectors, one for the wiper motor & the other has the back-up light wires.. The Blower & A/C clutch wires come out of the top two holes... BYW the blower wire has a typical single spade style connector about 6" from the motor...

Not that I like them.. I don't.. But Year One has harnesses for 70 & 71 A/C
