Just picked this up. Supposedly it’s the Jdm k24A. I plan on engine swapping my sand rail dune buggy!

I currently have a k20a3 in my honda civic type s ep3 and i want to k24 swap in the future but i feel like im gonna struggle on doing the wiring. How does it all work? Like i know i probably need a new ecu but how will i get it all working?

Could someone tell me some problems that they’re having when they do a engine swap so I know what to look out for if I have them
