im using SI U.S. spec ecu and wire harness in my 98 civic ex LSVTEC. i repinned most of the wires to make my fan, reverse lights, tach and speedometer work. eveything works fine, i had it like this for a year now..but i cant read the CEL codes-so i took the light out of the guage cluster for now.

question is

anyone using this setup?

anyone using a different wire harness?

im thinking of trying to use a 96-98 EX harness with repinned wires, but not sure if the plugs work on the SI ECU-anybody know?

TIA

I use my stock harness and an OBD2 P30 (96-97 Del Sol VTEC). Everything works 100%, no repinning anything.

so, anybody know if the 98 plugs fit the 99-00 si ecu(im repinning the wires) just need to know if they all fit


thanks

The plugs don't fit. You can get a conversion harness to convert the 96-98 --> 99-00 plugs. You will then be able to run the Si ecu.
