The easiest way to find the reverse wire circuit is to use a circuit tester like part # PTW2993.
If your back up light is a separate light at the rear of your Highlander, use the circuit tester to check the wire when the truck is in reverse. Have someone sit in the driver seat, set the emergency brake and put their foot on the brake pedal and then shift into reverse while you check the wires at the back of the light assembly for the backup light. When you find the wire that only shows current when the truck is placed in reverse, you can splice into that wire.
