swapping my stock si hatch into my 91 crx si

[KYL174]

recently, i just swapped in a type r motor into my hatch. and now i'm planning to swap the stock vtec motor from the hatch into a 91 crx si. what are the mods i need to make. some people are telling me that i have to modify the crx harness and have a obd1 ecu. what are my options???

you could modify it, but i would just rather go to a junk and find the harness. the engine harness is still on the engine right? So just grab the compartment engine harness at a junk or something. and plug in your p28. at least i think it'll do.
