Hello everyone, I need a pinout for C101 connector (this large white plug behind the glovebox that connects the engine harness to the chassis harness) for the 04-05 Civic LX Sedan, although I think it is the same for all the 04-05 Civic 1.7's and I would greatly appreciate any diagrams you can provide as I am only able to find a diagram for the 01-03 Civic. I am currently prepping for a K24 swap and I need this diagram to repin the K20 engine harness to work in my Civic. Thank you very much in advance!

Compare the '01 pinout to yours to see if they match, I think they will.

There's also a stickied thread with a download for the factory manual with all the wiring diagrams....

Hi, Could you, please send that diagram for the 01-03 Civic, for the C101 connector?
Thank You.
I just have listed the colours:

NOTE: The numbering was given arbitrarily dued to the fact that presently I do
not have any other information.

The half side (01 to 10) has a plastic connector holder attached.

Hi Mr. BrotatoChip,
Thanks for your message link.

In order to rebuild the harness from the Secondary O2 sensor (have a new one) to the vehicle harness, (the male plug was riped-off by helliens), assuming they possibly go directly to the ECU, I need to identify the pinout of the ECU 37820-PLA-G01 (KEIHIN CORPORATION), that belongs to the vehicle:

HONDA CIVIC 2001-4DR(ES4)
Version 1.4S
Transmission 5MT
Power 66KW
1396 cubic centimeters

Note: I used the pinning numbers of the receptacles females but in some places, other order is used, maybe of the males? I believe only one is correct.
Furthermore, the marked ones with two asterixes ** : Needs colour name check dued to harness with 21 years of age.

The list with the cable colour is done. It is necessary to identify the Function Names:

For each of the five: Which name of the function? To which position?:

1.Secondary Sensor O2 signal (live) goes to the central wire of a coaxial cable;

2.Secondary Sensor O2 signal (live) ground of the above coaxial cable;

3.Secondary Sensor O2 signal return (different from the ground of the coaxial cable);

4.Secondary Sensor O2 heater line positive;

5.Secondary Sensor O2 heater live negative;

I am not going to be any help here. If that info isn't in the service manual I posted a link to, there's nothing more I can give.

Hi Mr. BrotatoChip,
I found some more information and I compiled a corrected list.
I believe there is no colour mistakes and I put the numbering sequence like in the manual.
I'm on reading some more information to find the return cables exactly and looking for a more complete version of the manual.
The Chassis and Engine codes of the models are pretty much mixed in a way that looks more a puzzle than I would say a Good American Manual, with all the information, it normally brings.
Who gives what he/she can's to no more is not obliged.
Take it easy.
Furthermore There are more tides than sailors, if you know what I mean.

Merry Christmas.

Best Regards.
