A windscreen swap is required, anyone saying you can remove the prism from the original screen and fit it to a non RSW
successfully, is talking out of their hat
A ZCS coding change is required, and a bit of extra wiring from the (hopefully) fully populated plug at the base of the A pillar, I have done this on my old man's car as a broken windscreen was replaced with a rain sensor version
My advice is not to bother, one of my cars has rain sensing wipers, three do not, and I find the two rain sensors placed either side of my nose more than adequate to know when wipers are required
