Ok so Im going to convert my truck to power windows. I have the regulators, door panels, and switches. What would be the best way to make it work. Can I just piece together the harness (I grabbed the plugs when I got the regs and my switches also have wires). Could I just run the electrical to some relays and then to the windows.

 

I've been running power windows & locks for some time now ,used all 4 runner stuff( used whole doors) as wanted one piece side glass!
Just recently I changed the control switches to back lite ones (from Electric Life) & did away with the 4-runner relay that has timers in it. I still run power from the 4-runner circuit breakers that I wired into the main fuse panel. Run all my own wiring.
Get the Electrical Diagram book for your year truck from Toyota ,very handy!!
