I just bought a 65 impala ss with non-functioning wipers. Previous owner swears the wiper motor is recently rebuilt, but couldn't figure why it didn't work after installation. After a little tinkering verified it had no power to the unit and after referencing my trusty wiring diagram I discovered why. The black-yellow stripe wire that is supposed to provide power was not connected and stuffed behind the wiring harness. Guess he didn't know what to do with it so he hid it. Anyway, problem is there is no open connector on the motor. I know the middle terminal on the motor is the +12v terminal, but is connected to the three conductor connector coming from the switch. So I don't know if I have the wrong wiring harness from the switch (doesn't look like it), the wrong motor (probably, but physicall fits), a missing connector that broke off some how (doesn't look like it). Assemebly and service manuals don't have enough detail to determine where to connect the power wire. Anyone out there have suggestions? Should I just splice the wire in?
