Another wiper motor question

[HIGHWAY BY THE SEA]

I just bought a new wiper motor for the 67 GMC 3500 that supposedly has the pump in it. Here is what they sold me:





Here is the one that is already in the truck:



Notice that the one in my truck has the three bladed connectors, and two more bladed connectors apart from those. The new one has the three bladed connectors, but not the extra two separate ones. Did I buy the wrong one, or is this some modern upgrade? This new one looks NOTHING like the old one.
