I know this has probably been mentioned several times but I cant seem to find the answer when I search. . . . I have an 87 crx si that I am swapping the engine out from a donor 87 integra, from what I've read I dont think I will have many problems with the swap but wiring is not the best thing I know how to do. I have read that in order to do this I need to swap 1 wire but which wire is it? I have both complete cars only the crx's engine has seen better days and the teg needs a fuel pump. I have to do the swap this weekend so I can be at work monday so any help would be GREATLY appreciated. The more specific you can be on the wiring the better. Thanks in advance.

Here's a link to a nice write-up a good friend of mine put together:

Thanks man, great link. The swap went great and the car has way more pep. I am having a little trouble with the cold starts though, I have to give it gas to get it to start, anyone else have this probloem after the D16 swap??

is it carb'd or FI?

Carb'd, check the choke, FI, take off the IACV and clean it out, or just replace it.

Also, I think you were supposed to change the fuel pump, etc, if you were going FROM carb TO FI... if you didn't do that, I'm surprised it even starts.
