Help needed badly

[K20CL9]

Ok so i need some help


I have a 2003 Honda Accord Type S (Its the EDM one same as TSX)

It currently has a k24a3, which i ended up hydrolocking... i've bought and fitting a k20a from a DC5 integra.

I need to know what k-pro setup i'd need to run in order to get this to work, i know i need dual harness but as i'll be using the PRC ecu from the dc5 what else do i need to do.

Im confused, i'm trying honda for a reflash of my current ecu but as of this far no luck... i've got one company left to try before i have to folk out for k-pro.
My other option but im not sure about this is to fit a RBC-J01 ecu outta a Euro R Accord from japan.
As they run the same K20A and have the same setup inside so i imagine that would be the ecu to get hold of.
Thanks,
Tom
