there is a 3 wire plug on the civic harness going to the crank pulley. but there is a 4 wire plug coming from the h22a4 crank pulley......also the dizzy on the h22a4 is external, what do i have to do to wire this up? I have heard something about getting a internal dizzy from an earliar model prelude....how hard would that be to wire up. I'm trying to wire up my buddy's car. I told him I could wire any b series but knew nothing about h series. Please help!!!!!!!!!!!!!!!!!!!!!!!!
