i found the stuff to convert my crx over to power windows
only thing it doesnt have is the dash harness
so do i need the dash harness to convert my car over to power windows?

 

Here's a thread from the FAQS using slightly different parts maybe: https://honda-tech.com/forums/honda-crx-ef-civic-1988-1991-3/power-window-install-w-spal-window-kit-1222469/

 

That's a good thread, just missing the diagrams. You will probably have to make your own harness to whatever you have for the doors. I'm assuming JDM/EDM? If you have door-mounted belts there may be a conflict with the connector pins. I was going to use civic sedan parts and integra switches but sold the car.
