B20B engine harness help
 

I'm taking out my B18A1 and selling it so I can put it this B20B... I read I could use my original engine harness with my i/h/e just to get by, but if I used a obd2 harness I would get more out of the B20 cause its an obd2 engine... Do I need to use a manual obd2 harness or the orginal crv harness... Also can I just use a obd2 to obd1 jumper harness and keep my ecu? Can anyone let me know which is the best way to have a B20 dropped in... I'm sticking with stock for now... any help is appreciated... https://honda-tech.com/forums/images...es/emsmile.gif
