Does the 4th gen S model Prelude come with wire harness for a swap? Like swapping in a Si or VTEC motor. If I swap a Si motor into a 92 S do the ecu just plug right in? I wanted a Si but I am getting a great deal on this S model. How simple is it to swap a H23A in there? What all has to be done. Thank you.

I tried searching, but they are all about H22A and didn't provide enough information. Thanks.
