I was wondering what year Si harness I would need to plug and play an 97 ITR and ecu into an 00 EK.

Also, where can I get a downpipe to link a JIC Spartan Type 1 exhaust to the ITR exhaust manifold.

Thanks in advance.

As far as I know the 99-00 Si (or Ex VTEC) harness should be plug and play, with minor modifications (like extending some plugs) since it's an OBDII motor going into an OBDII car. I have a 00 GSR in a 00 EK, and I went by the instructions found here (thanks Katman):

I also got a conversion harness to convert from OBDIIb back to OBDIIa because the 00 GSR ECU always threw a CEL because the immobilizer is removed. So, I got a conversion harness to run a 99 GSR ECU (OBDIIa), and no CEL's since. You might have to do that as well because IIRC everything up to 00 is OBDIIa.

yeah, there's actually only 1 type of Si coupe harness which is 99-00 (OBD2b) and will plug n' play into an 00 EK civic with minor mods...

You have to extend wires for the injector plugs, and I believe the IAT sensor and the sensor that sits right on top of the intake manifold will need to be extended as well. Not sure if the ITR uses the same setup as the GSR (secondaries/butterflies), but I had to wire that sensor directly into the ECU. You will also have to wire in the secondary o2 sensor as well.

Basically, all the info you need is in this thread:

Yeah i dont think they are the same, i've only heard about that when referring to GSR motors

would i need a new downpipe to link the jic exhaust?
