I'm putting a b20z into a 92 hatch. Should I use a conversion harness or will a obd1 dizzy work with the b20z.

Also will my current harness work with the b20?

Thanks guys

 

I've been researching the B20Z for my car too. You can use a OBD1 B18B dizzy. You might be able to reuse the harness from your Civic, depending on what model you have. Not 100% sure if there are any sensors on the B20 that have a different plug because of OBD2. An OBD1 B18B harness might make things easier. It will plug into your shock tower plugs. Hope this helps some.

 

OBD is determined by the signal the ecu send and nothing more. Only difference when it comes to obd1 and obd2 dizzy's, injectors and alternator is the plugs so yes you can use a obd1 dizzy without any issues with your stock civic engine harness.

No point in using a b18b engine harness. It will be almost identical to your civic harness if not identical, therefore a waste of money.

 

Yeah I was basically wondering if needed to get all obd2 ****
I understand I can use my harness with obd1 but the b20z is obd2
Thanks though I think I got it

 

I did use a OBD 2 engine harness when I did my GSR swap just so I didnt have to find OBD1 injectors, alt, dizzy since I already had all that with my GSR swap and the OBD2 harness made everything plug and play.

 

Yeah I have obd1 dizzy already and obd1 harness so I'm just gonna get a obd1 mani since I need one neways

 

What model is your hatch? DX, CX, VX, SI? If its DX or Si you can just reuse your injectors.
