OBD2b head and a OBD2a wiring harness...
I have a 96 hatch and the head I am putting on is off a Civic SI. Will the injectors, and sensors plug into the OBD2a harness? I will be running a obd2 to obd1 jumper and a phearable Ecu. I need to figure out any possible issues now before I do the swap. The bottom end is a JDM 96+ block.

I know that. Anyone who thinks a DOHC motor will fit on a SOHC block is an idiot... My concern is with the head and the sensors being able to plug into the wiring harness on my car. I know the bottom end I have will work fine.

your information you have posted is not enough to give a correct answer.
and there are people who think a dohc head will fit on a sohc engine....and it is possible...with money anything is possible....
all obd2a and obd2b sensors should be the same....injector plugs the same tb iat....

My question had absolutely nothing to do with the block. I just wanted to know if my OBDb head would work with my OBD2a wiring harness. How much more information do you need to know to answer that question? Not trying to be a dick, just don't understand why this has to be so difficult... Thanks for the help.

Re: OBD2b head and a OBD2a wiring harness... (Whatever)
we don't know what block you have....we don't know what head you have....there are lots of IDIOTS who would think they could throw their b16 head on their d series block. And without the proper phasing of the question they might read into that question and think a 99 ob2b head will fit on their 96-98 obd2a d series block!

Your over analyzing dude... What block I have has nothing to do with the question that I asked. I said I had a OBD2b head off a Civic SI, maybe I should of said a 00 B16 to be more clear... Again thanks for taking the time to answer my non specific and incorrectly phrased question though!

Re: (Whatever)
Tell me....What obd2a CIVIC came with a block that would allow an obd2b civic si head to be bolted to it???
EXACTLY!!! NONE IN THE US....so therefore my "over analyzing" wasn't really over analyzing now was it!

When did I ever say it was a OBD2a Civic Block Sherlock? The bottom end I am using has ABSOLUTELY NOTHING to do with the question I posted. If I felt like it was important I would of said, "it is being bolted onto a JDM B18C block". But I only wanted to know about the sensors on the OBD2b head plugging into my OBD2a wiring harness. If some idiot wants to draw some other conclusions about what block I am running then so be it. You were smart enough to answer the question without that incredibly vital information weren't you? Damn you're hard headed...

96-00 hatches all had non vtec engines therefor non vtec harnesses. so no ur obd2a harness in ur civic will not just plug right up and work. if u have a obd2a vtec harness then yes it will work. pretty sure the only differences between obd2a and b is a fuel tank pressure sensor and the connectors that plug up to the ecu.

I had a feeling that was wrong... I was going to say JDM ITR block but then he might of complained that people didn't know what a ITR was...

I'll have to do some research on this. I know I also need to run 3 wires through the firewall in order to get the VTEC wired up as well. If it's only one plug that needs to be modified then I don't think it's worth picking up another wiring harness.
Thanks...

Re: OBD2b head and a OBD2a wiring harness... (chad)
Obd2b head = more pins then a obd2a head.
Solution?
Rewire it and might be half ***. Or...
get a obd2a dizzy and use that on your obd2b head
Rywire Obd2b Dizzy conversion harness to Obd2a.

Re: OBD2b head and a OBD2a wiring harness... (bokals)
The guy I bought my head off of had started to rewire the Distributor for an OBD1 harness so I need to figure out how hacked up it is. Might be easiest to just buy a OBD2a distributor since I can get parts at cost. Are all OBD2a B series VTEC distributors the same?

Re: OBD2b head and a OBD2a wiring harness... (Whatever)
you need to go off of what your engine wireharness is....there are 2 different plug ends for the dizzy's....i don't recall off the top of my head which is which...
see how hacked it is....it should be easy to convert back...
