I would probably go for engine and disconnect to ECU both. There are several adaptor harness's out there for that swap - that is where I would start the planning around. Get a good adaptor harness and fill in the gaps.

What engine is in the donor car? D16A1?

my civic had a d16a6 in it b 4 the integra doner car has a b18a1

I modified my Ef harness for my b18. Also ran a p28 with a obd0 to obd1 jumper. U will need a new throttle cable bracket or just a Ef to b18 cable. U will need a traction bar to make clearance for your exhaust. Also u can cut n weld your linkage or hasport makes them for like 125.
