OBD2B to OBD1 questions
Say I have an 99 Civic ex OBD2B and I want to convert to OBD1, would I only need to get an OBD2b to OBD1 jumper? My distributor is obd1, so an OBD2b to obd1 distributor adapter would be necessary. Or now matter how i look at it Im still going to re pin and the ecu plugs? Any help is appreciated!!

Re: OBD2B to OBD1 questions
Yep, you're on point. You'll need an OBD2B to OBD1 ECU converter, as well as a distributor converter. Alternatively, you could just get an OBD2B distributor that works for your motor. I'm not totally familiar with the H22A4, but if it uses a 3 wire IACV, you'll also need to convert it to a 2 wire, which is relatively simple.

H22a4 has the crank position and TDC located by the crank pulled and not in the distributor. So with that being said everything should jus plug n play? Or because the obd1 distributor has those sensors inside, I'd have to re pin at the ecu connectors?
