That is just for the civics and integras. The Preludes and Accords don't have the CKF(crank fluctuation sensor). The H23 dizzy you have has a 4 wire plug and a 2 wire plug correct? That means that only one of the three sensors needed (CYP, TDC, CKP) are in the dizzy. The other two are on the oil pump and use the timing belt gear and balance shaft pully to read from. The JDM H22 dizzy has a 8 wire plug and a 2 wire plug. This is because all three sensors are in the dizzy. You will need to run the wires in the engine harness that normally plug in down by the oil pump over to the dizzy and use the JDM H22. You will also be changing from a external coil to an internal coil.
