Okay i have a 94 s model prelude which i just did an auto to manual conversion and a f22a to jdm h22 swap. I used an h23 engine wiring harness and wired up vtec. Do i need to run i wire from the Knock sensor to the ecu and the Iab sensor to the ecu also?
I started it up yesterday but i need to diagnose why my battery isnt charging and i have a cel also i need to pull the code and see what it is. Someone has to have done this swap before and any help would be great. Thanks

 

I swapped an F22 for a JDM H22 (complete swap though) and only had to wire the VTEC and knock sensor to my P13 ECU. No problems or CEL now.
