Hello. I have a 99 DX and i swapped in a 98 EX VTEC. Just to get it running i had to splice connectors from both engines and use my old ECU. So now i have a loping idle and a CEL and VTEC is not hooked up. Now i learned the 98 EX is a OBD2A and my 99 body is OBD2B and i need a ECU jumper harness which i bought. From what i understand now i have to convert my IAC connector from 3 to 2 wire. Also i need to wire up VTEC to the harness but i dont know how and i dont know where to find info on that. And some say i have to extend or swap the krank sensor connector but info is unclear on that. Any more information i can get will be great.
