How do I wire a toggle switch to run a power window motor in both directions?

Per the diagram, connect battery positive (red) to the middle terminal on one side of a six-terminal switch and ground (blue) to the middle terminal on the other side. Then cross-jumper the outer terminals in an X pattern (red from top-left to bottom-right, blue from top-right to bottom-left). The two wires from the bottom terminals go to the window motor.

Where does the positive wire connect on the window switch?

The red wire labeled 'Positive- To Battery' connects to the middle terminal on the left side of the switch.

Where does the ground wire connect?

The blue wire labeled 'Negative- To Ground' connects to the middle terminal on the right side of the switch.

Which wires go to the window motor?

The two wires (one red, one blue) coming off the bottom pair of switch terminals are labeled 'These two wires go to the window motor'.

This document is a simple hand-drawn (computer-drawn) wiring diagram showing how to wire a power window toggle/rocker switch, uploaded to the gallery of a 1979 Ford Bronco. It depicts a six-terminal switch (typical DPDT momentary rocker) with power and ground connections and a cross-wired (X) polarity-reversal pattern that allows the window motor to run in both directions. A red wire labeled "Positive- To Battery" attaches to the switch's middle terminal on one side, and a blue wire labeled "Negative- To Ground" attaches to the middle terminal on the opposite side. Inside the switch body, jumper wires cross diagonally: red runs from the upper-left terminal to the lower-right terminal, and blue runs from the upper-right terminal to the lower-left terminal. Two wires (one red, one blue) exit from the bottom pair of terminals and are labeled "These two wires go to the window motor." A reader can learn the standard reversing-switch wiring scheme for a power window motor: feed battery positive and ground to the center terminals, cross-jumper the outer terminals, and take the motor leads from one end of the switch. The diagram contains no year, model, part number, fuse, or wire gauge information.
