I have been researching my swap (B16a3 into 92 cx) and I have a question about the wiring. I have read a number of contradicting things about the wiring. I have heard that only the VX and SI are wired for v-tec. Also I heard every model in 92 is wired correct. I also read that you only have to wire the knock sensor. What is fact and what is fiction? Thanks!
