I'm getting ready to drop a H22 into my 91 crx. I was wondering what kind of changes I'll have to do yo my wiring harness since this motor has an external coil. The motor was last ran in an 96 ek coupe so its most likely a obd2a plug. Wil I have to make some sort of jumper harness for the dizzy?

 

Buy a jdm h22 with a internal coil from me . Your going to need to upgrade to obd1, Xenocron his what you need. Alt wires need to be made longer. Mod Chris has a top hat type thing for the stock intakemani that would also make wiring a bit easier. Also the vtec/ pressure. Thats all that comes to mind.
