I am having an issue with my dizzy. I swapped out my JDM H22A and am putting in an F22A1. The F22A1 has an external dizzy and the JDM H22A has an internal one. I really need to get this figured out so I can get my car out of the garage. I'm wondering what process I would have to take to wire up the harness to the dizzy and to get the dizzy to work properly. I already know of splicing wires, but I believe that is for cars going from an external to internal dizzy.

From the Swap FAQ
Internal/External Coil Issues:
If your car came equipped with an internal coil then the JDM H22 distributor will plug right in no problem. However, if your car had external coil then you will have to modify one plug. The plug you will need to modify is the plug that went to the stock coil. There are is a yellow and a yellow/black wire, splice those 2 wires together. The Black/White wire is useless, don’t worry about it. If you dont want to cut the plug off and splice, jam a 30amp fuse into the end of the plug, making the connection between the two wires.
If your car is external coil and you wish to maintain the external coil you will need to open the JDM dizzy, remove the internal coil. Run the wire from the igniter that used to go to the internal coil out of the distributor and plug it into the blank spot on the distributor’s plug. That’s it. Use the 93-95 Prelude Vtec’s Distributor cap and rotor that you can pick-up and your local dealer or auto parts.
Hope that helps!1992 Prelude S w/swapped H22A
