Need help with ideas for power windows/locks/sunroof.

[pella]

I’m in the process of building a track car. It’s a 95 S4.5 with a 5.0 in it. Its been a very long project and still wont be complete anytime soon, but its coming along. At the moment the dash and harness is out. Not much of it will be going back in. I have some questions about what others have done when they gutted their car. The car has power windows/lock/sunroof. Looking for possible ideas, options and what other people have done to still have this functionality. Im open to ideas and suggestions.
