Internal/External dizzy question

[TheTempest]

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 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.

I had a few questions reguarding this.

1) I believe my F22a4 is an external dizzy, would someone mind verifying for me?
2) How do I convert, assuming it is external, my external dizzy to an internal for my h22 swap?

Thanks in advance.

Ok your F22A4 (90-91 EX) is already internal coil. Even if it where not there would be no conversion needed, you would just plug in your internal coil dizzy and jumper the yellow with the yellow/black on the coil's plug. All this is covered in the FAQ.
