okay so I’m really reluctant to even post this because I know someone is going to get mad but I’m out of options here. I have an 89 crx dx. Still has the stock d15b dpfi. I just bought a 98 integra as a donor car. I’ve read up over and over on the wiring and I’m still confused. I know the engine is Obd2 and I’ve read that to take the engine to obd1 I just need to get an obd1 dizzy, alternator and injectors to be safe. I got the whole parts car for $475 and the ecu is bad which is fine because I would need an obd1 ecu anyway. What I don’t get is do I keep my harness and do an mpfi conversion and THEN get the jumper? Or do I buy an LS obd1 harness and feed it to the new obd1 ecu and not worry about mpfi conversion since the obd1 integra harness is already mpfi. I’m really hoping someone can explain this to me in a way I can understand. I’ve come a long way in rescuing my little crx! I just need some help with this part ❤️

Keep your harness do the mpfi conversion and get the obd1 jumper you can run the obd2 stuff just get the jumpers I did a b20 swap on mine I have an obd2 alternator, dizzy, and injectors and it runs great

For my injector airing I went to the junk yard and grabbed the injectors and cut some of the harness from a da and used that here’s a pic of what it looked like
