I had to put a 67 upper cowl on my 68, so I have a 67 wiper motor with 4 posts, not 3. My AAW only has directions for a 3 post. It looks like the first 2 spade terminals (from the drivers side)are joined togther for the yellow wire(12 volts), then the third is probably the light blue wire, then 4th is the black ground. Is this correct.

I have 5 posts on mine. From driver to passenger mine goes: double yellow, green black. Then the lower two terminal connector is yellow and blue.

5, is that including the washer pump attached?

Yes.

I have a 67 with the AAW update wiring harness. On mine from drivers side to passenger side the top 3 wires are white labeled wiper feed, light blue labeled wiper high speed ground & black labeled wiper ground. On the bottom plug for the washer they are dark blue labeled washer ground & white with the white power wire coming from a jumper on the top plug. This was done according to the wiring diagram that came with the harness as well as the schematic that came with the new wiper motor. So there are a total of 5 spade terminals on the motor itself which are connected by 4 wires with the wiper motor & the washer pump sharing the same white feed wire. http://i248.photobucket.com/albums/gg163/nhbandit/Wiperwiring.jpg
