I have a b18a out of a 90 integra that I'm planning on swapping into my 91 standard hatchback. I have the option of buying a totalled crx si for about 200 bucks (not sure on the year, it's 88-91) and a friend told me that the engine wire harness will connect to my car and to the b18, and that I could use that ecu. There are a few other minor things that I want off of the car, but the main thing I want is the wire harness, so that I don't have to rewire anything.

Can anyone tell me whether or not that wire harness and computer will work in my swap, or would I still have to rewire it?

Thanks in advance for any information.
