First post long time browser of forum. Hello forum and thanks in advance. My issue is my window switches have blown out, being that i have a 1970 vehicle i cant find after market switches anywhere so that said how do i wire two 3 prong switches(on/off/on) for left and right windows, relays and connect straight to the window motors.

On the diagram, to actuators = to window motor.
Alarm lock and alarm unlock output = wires on outside terminals of your switch. Ground the middle leg of the switch.

Make and model of vehicle? How many wires on the old switches? Some power window motors had an up winding and a down winding, whereas some are reverse polarity.
