besides the self explanatory power, I.E. the wiring and switches. you will need the window motors and probably the regulator ( they may come as a unit motor and regulator ). for the locks the same applies for wiring and switches, plus the actuators.

have you checked to see if the 99 stuff will bolt in?

if it will then I would get motor and regulator, actuators, switches. the wires themselves are not as important as you can run your own wires and it is fairly simple.

have you compared this to the universal kits like autoloc offers?

I have an 88 crx si with power locks and windows, I added express up and down on the windows and the sunroof as well as a single push button that opens, and another to close, both windows and sunroof.

you can do some trick stuff with basic automotive wiring knowledge.

are you going for a factory look or custom? ( not that 99 power features in a 96 isn't custom, but you know what I mean )
