I just purchased a 1996 Honda Civic CX Hatchback. The car has a mini-me swap with d15b7 bottom, d16z6 head, and a p28 ecu. There is no jumper harness as the seller never finished the project. Would I just need to buy the ecu adapter harness from rywire/chasebays and be good to go? The car will be equipped with a B20vtec later in the year.

To the top.

wouldn't even bother to waste the money unless your keeping that engine for something.

coupatroopa

What is your reasoning for this?

CivicSpoon

Yes, you should just need an OBD2A to OBD1 conversion harness, to plug in the P28 ECU.

coupatroopa

Cool. I guess I will contact rywire and order one today.

I just picked up the car and it does not have the harness that runs from the ecu to the engine harness. Does anyone know where I can locate one?

well u can do kinda cheap

1. u can get any cx harness from junk yard and do it right(just the section u are missing)
2. u can find the correct ex harness plug and play to vtec harness
3. find any harness and try and make work but can be a bitch with all the other models with diff engine harness

the 40 dollar ebay conversion harnesses work perfectly fine and you could save 100 bux. wiring vtec is not that hard to do and many wire ups on this.

coupatroopa

Are you talking about the ecu conversion harness. Because I also need the harness that runs from ecu to engine harness.

I am putting in a OBD1 motor in this car. Can I just use the d16z6 engine harness?

CivicSpoon

Exactly what harness are you missing? The 6th Gen Civics ('96-'00) use a 1-piece harness, that runs from the ECU straight to the engine. Where the '92-'95 Civics and OBD1 & OBD2 Integras all use the 2-piece harnesses (ECU to shock tower harness & the shock tower to the engine harness).

coupatroopa

I was thinking it was like the 92-95 civics. That is all I have had. So I can just use the one out of my 95 ex coupe? I have a parts shell sitting here that I can get the harness from.

CivicSpoon

Technically yes, but it's way more work than it's worth. You'd have to swap over the entire dash harness as well, meaning you'd have to rewire a lot of things; like the gauge cluster, clock, rear defroster, etc. So realistically, you'll need a '96-'98 Civic harness.

coupatroopa

For a obd1 motor?

coupatroopa

Is there any good write ups on this?

coupatroopa

I have located a 98 y8 harness.

coupatroopa

Turns out that the harness has been cut. I am looking for a uncut harness.
