Ok i plan on adding power windows, locks, and keyless entry to my truck. For the windows, i figured i would get the door panels from the junkyard (they have them for $40 a piece) That is from an SR5. Then get the power regulator (motor included) from autoandart.com, which they sell for $75 a piece and $15 shipping, so $165 shipped for both. And i figure i can pick the harness up at the junkyard as well, which will take care of windows and locks. What i want to know is, for the windows is that all i need (regulator w/motor, switches (entire panel), and harness), and for the locks, do i need just the actuators, switches (entire panel, as stated for the windows), and harness (as stated for windows)? Are there any modules or the like required? I have experience with wiring, and would be able to wire up stuff if need be, just need to figure out what all is required for the job.

 

This should help. First, the windows:
