Re: 67 RS Wiper Wiring (Again)
Treat the YEL wires from the painless harness as the factory BLK/YEL wires. To confirm this, there should be 12 volts at the YEL wire when the igintion is on. There should also be a DRK BLU wire on the harness, for the pump operation.
To make it easier, let's number the terminals on the motor, from passenger side to driver side, 1, 2, 3. On this motor, ignore the last terminal (driver's side) since it's already a double lug connection. Let's also ignore the plastic harness connectors for the moment and concentrate on the terminals themselves. The BLK wire connects to #1. LT BLU to #2. YEL to #3. The painless connectors should allow the terminals to be connected only one way as described above.
For the pump, the DK BLU wire, if you can find it, and the other YEL wire connects on the those two terminals. If you don't have a pump, just ignore those wires.
It sounds like you have a late model wiper motor. Is there a plastic cap beneath the terminals? If there is, then the cap has to be removed and the wiper pump cam installed on the protruding shaft.
Hope this makes sense!
