adding windows to replace manual

Easiest way would be to go get the switches and harnessess off another one in a junkyard. If thats not possible, you'll have to at least get switches from somewhere, even if you end up getting aftermarket switches. If you get the factory harnesses, get all wiring inside the door and you can just cut it at the doorjamb boot. It should be like 4 wires. I'm not too familiar with toyota wiring, but I've done this conversion on several GM cars and trucks. The harness has a ground(which I grounded inside the door), a power(which I wired to ign),two wires to the motor, and three wires which you have to extend to the passenger door harness. Those three are 12v power, window up and window down. Those three go to the switch in the passenger door.The wiring from the switch goes to the motor.

70% installation, 28% product, 2% luck, try to be the best everytime!

I did two trucks like this and a few cars. Both trucks were old work trucks that the owners were restoring and had new doors with power accesories in them, I wired it all up to the truck. Power locks, power windows, and power mirrors, I think the mirrors were the hardest.
