Re: how do I wire toggle wipers?
Not sure about '69, but usually there is not a ground wire. It picks up the ground through the wiper motor case. 3 wires would indicate a two-speed motor. One wire for high speed, one wire for low speed and one which is only hot with the switch off so that the wipers can automatically park themselves.
Do your wipers have 2 speeds?
