I was wondering exactly what needs to be done to run a obd1 motor in a obd2b car? i know you need the ecu a jumper harness and the distributor repinned. But there must be more cause my car won't start. It's a 99 civic dx with a JDM 94-95 B18C in it. I've got the complete swap from hmotors so i should have everything. Any help would be appreciated.

use your d16y7 harness. You'll need to wire in vtec, IAB (or just wire it with vtec) and possibly a knock sensor.

your b18c dizzy will need to converted to obd1. then you'll use an obd1 ecu with a obd2b->obd1 jumper harness

don't repain anything just get and odb 2 distributer and your good. but the vtec you defeatnetly you have to wire that up and knock sensor

you need a 99-00 SI rear and timing side motor mount
use your stock harness and modify it.. change from 3 wire iacv to 2, and add vtec, knock and IAB. its all simple.. or find a 99-00 SI harness or 99-00 EX harness for a direct plug and play(may need to extend a few wires)

you will need obd2 injectors and alternator if you want it to plug and play... you can use the obd1 distributor if you re pin it or find a obd2 one
jumper harness and a obd1 p72 ecu

cool guys yeah i'm running a 99 si harness and a jumper harness from h motors if i use a obd2 dizzy do i have to repin anything? cause h motors said i couldn't do this, also about the alternator i just switched the connectors on the harness's so it would plug in is this wrong? thanks for the help guys

Maybe it's because your knock sensor isn't hooked up.

The car will run, and drive without a knock sensor.
