Why exactly do you want to do this? Do you realize the B18A is non-VTEC and makes less horsepower than the B16 you already have? Instead of doing a full swap, I'd just keep your B16 head, and swap out the block for a B18. Then you'll have a more powerful motor, with higher displacement, and you won't have to do any wiring changes.

That does seem kind of backwards. If you really want to downgrade all you have to do is get the computer that corresponds to the motor you are using and trace back the four wires in the vtec sub harness to the ECU plugs and cut them out. Or if you wanted to be lazy you could just un-plug them and tape them out of the way. (Although I discourage this swap as well.)
