iv been searching about this, i only swapped a ls into my da before, when it comes to wiring i dont know what to do, i dont even know how to converte to odb1 , i am thinking to do a h2b, i already know everything about the swap except for the wiring and ecu

here is my plan

jdm h22a , qsd kit, stock ls tranny. i am thinking to keep all the emisson stuffs to make it smog legal.

do i need a manual 92-95 prelude ecu? so can i just unplug the old one from my 90 odb0 teg and plug whichever ecu i need onto the old ecu harness?

would it make a different if i have a 92-93 odb1?

do i use the old engine harness for the h22 block?

what do i do for distributor, alternator, fuel injectors, and other sensors?

i am so confused , pls give me a hand


thanks guys
