I posted these in the hybrid forum, but this will ensure they come up in a search.

These include ECU pinouts, sensor identification and location, and wire harness routing.

All scans are high res and can be printed full size on paper from a good image program. Do not print them from Internet Explorer.

If you find these useful, please purchase a Helms for yourself at http://www.helminc.com
They literally pay for themselves the first time you use it.

2000-2001 ITR
This can be used for older ITR's as well, but the ECU will be different. Please refer to the EX ECU pinouts for the correct pinning of the 96-98 ITR ECU.

Thanks Tony, this could be useful when I do my ITR swap. 96-98 EX same as DX harnesses?

 

The diagrams cover all the Civic models in those years - DX, CX, LX, EX, etc.

 

The ECU scans cover all model years, but the harnesses are slightly different. But the end results needs to be the same.

 

have any for the 93 cx i own?
im tryin to wire a 4 wire o2 sensor so it can take out the check engine light? code its throwin is 41...
Yes im still using the cx harness unless you guys know somebody sellin a 95 ls engine harness uncut obd1, then i take it....

Thanks.

 

Sorry, I am not taking requests for any Helms scans. I only posted those because I scanned them for my use so that I could write on them. Those are the only ones that I have scanned and will scan.

 

its cool i guess, but is the ecu harness the same as those? or is it the same as the 95 integra gsr, ls??? just want to know so i can hook up some stuff to it you know... thanks.

 

It should be similar to any honda 95 and earlier. OBD2 starts in 96

 

Does the 96-98 diagram work for an automatic?

 

I know the ECU pinouts are there, but not sure about the harness.
