I've recently purchased a '95 EX coupe. I've been looking all around for any info on the wiring needs for dropping in a B16A2. I've found wiring diagrams that help people without VTEC already wired, but I already have it. Is the wiring required for the B16A2 VTEC the same as for my SOHC VTEC? If the wiring is essentially the same, can I just switch the ECU and the engines without any wiring issues? Thanks for any info anyone can give.

all you have to do after swapping the motor and ecu is run the knock sensor wire. btw is it the 92-95 sir2 b16a or the 99-00 si b16a2. if it the sir2 the motor will drop right in, if its the 99-00 si then there is some wiring that needs to be taken care of and also some mounts will have to be changed to integra ones.

I'm sorry, I guess I should've said which one. I'm planning on dropping in the sirII B16. I'd like it to be as painless of a swap as possible. Thanks for the info.

that motor would drop right in no problem and everything connects right up. only thing you need to do is run the knock sensor wire.
