this is the same problem i came across doing a freinds car
This 1.4 for some reason has 2 OBD1 type ecu plugs
Easiest i felt was to get a OBD2a engine loom 96-98 Civic...anything like from D16y7, d16y8 etc...with the correct ecu pinouts format, ie the ones we have wiring diagrams for!!...and then get a OBD2a to 1 coversion harness and run a P28 or p30 ...
As long as the new loom you got has the Ecu pin set up of 32 ...31...16 pins...your good to go
Guessing this is a old post...and you must have sorted it now...Let me know please what you did...thanks
In cases like yours, there is nothing you can do besides make, or swap in a new harness.
Those cars had no requirement for OBD2 like other countries, so honda used up the last of the OBD1 stuff they had. The only OBD2 1.4l engines honda made started with the D14z1, and depending on the chassis, it was either an OBD2a or 2b.
