I am working on a 1972 240z (build date 11/71) with my son and we have hit a small snag with the combination switch. Everything about the switch is working well except the washer motor wiring. I press the button and nothing happens. Now, I know the pump works as it is new and I have tested it with a 12v battery. I have also tested the all wires on the switch, both on the connector and an additional blue/white wire that resides outside the connector and is currently unconnected. As it turns out, this blue/white wire that is outside the connector is the one that goes to 12v when the washer button is pressed (see pics with wire circled). I have no clue where it should be connected as there is no obvious connection point. BTW, the switch is unmolested, was fully reconditioned and works well. The car came to us largely as an unassembled project and we have made excellent progress to this point. I am sure I am missing some connection point for this wire but it is not obvious where to connect it. Any help is appreciated. Thanks.

UPDATE: I had great luck with the distributor offered by ZCARDEPOT. Super simple to install and it worked first time, right out of the box. Fun was had by all! While it is more expensive it does not require any change to the current wiring or ballast resistor. The one I posted from ebay above required several changes that I did not care to do.
