I bought an ek hatch and it has the harness from a DX so I went out and bought an EX 5spd harness but I came across something I haven’t come across before. The end that goes into the ECU has four plugs as opposed to 3 plugs as I have work on before. If someone will be so kind to explain what the difference is, it will be greatly appreciated. Thanks This is the one that was originally in the DX EK hatch This the one I bought from an EX 5spd coupe This the one I bought from an EX 5spd coupe This the one I bought from an EX 5spd coupe
You obviously didn't remove that harness from a 5-Speed EX chassis yourself... it is actually an AUTOMATIC engine harness ('96-98) and that is why the 4th plug is present.
