Default OBD0 89 CRX HF to B18A1 OBD1 which harnesses do I need? Will need to pass BAR

I have a complete running 93 integra I want to use as a donor. I'd like to convert to obd1 and do whatever else will help me get past a smog referee. Going to order all the stuff today and I don't want to make a mistake. Using swapshop. Do I need the obd0 to obd1 zerg jumper harness, distributor harness and o2 extensions?

I see some mentioning to use my HF harness on the b18, is that only because they don't have an engine harness to begin with? I'd like to use the b18 da engine harness. Sorry for my ignorance, I just can't get a solid answer, keep reading conflicting info and I want to order the stuff now, thanks.

Use your HF engine harness and make it fit the "B" series engine where necessary. If you don't want to change plugs like the distributor, you can buy an OBD-0 -> OBD-1 adapter for the dizzy. You will also need an ECU adapter harness... OBD-0 -> OBD-1. Use the ECU and distributor from the '93 Teg. Now you have a solid answer. Done.

What's the reasoning to not use the harness from the B donor? Just trying to better understand. I'd prefer to use the engine harness from the b18 since I wouldn't have to mess with injector pigtails, o2 sensor or distributor adapter correct?

When I did an e36 swap into my e30 I used the e36 engine harness, a premade adapter that plugged into the e30 chassis and got a BAR sticker that way. Wow 540hp supercharged B?? Didn't know that was possible lol learning all kinds of new things, thanks for your help, happy holidays.

The DA engine harness does not plug directly into the '89 CRX chassis harness plugs at both shock towers... so the question is, do you want to modify the CRX harness to fit stuff you can SEE on the engine, or would you prefer to modify the chassis harness plugs and wiring to fit your DA engine harness. CAUTIONARY WARNING: Just because two plugs slide together where the engine harness meets the chassis harness does NOT mean that all wires are properly oriented. You will need to be really comfortable with wiring and have both the '89 CRX and the '92 DA Integra factory service manuals to compare the wiring diagrams.

Ah perfect thank you! I get it now. On the e30 the engine harness went directly to the ecu and the other half went to the chassis with an adapter cable right at the firewall. First Honda swap can you tell? Lol. Just ordered innovative steel mounts 75a, innovative shift linkages and innovative pro traction bars. Along with obd0-1 ecu and distributor adapters. A 36" 4 wire o2 extension just in case.

Got a couple cars I need to sell, then all PCI spherical bushings and ground control coilovers. After than a small turbo setup with 300whp until I can build a spare sleeved short block.

Do you have a link to that 540hp supercharged B? Quick google search didn't pull up anything, thanks again!
