?????

 

So long as it's a '92 (they're the only ones I know for sure always came with VTEC, etc.) it should be wired with everything. It's been a long time since I've played with the factory '92 CX wiring harness so I can't be sure. If you wanna double check it before you start the swap just check the pinouts for the oxygen sensor heater, if it's there then you're fine, if not then you'll need to add it in. I made a diagram a long time ago for the conversion so if you end up needing it let me know and I'll load it up.

 

could u post it please

 

This should cover just about everything but if you have any questions let me know. -Adam
