Obd 2a ECT to Obd 2b car

[webink_EK9]

Anyone know how to wire this. I've got a 99 Civic HB and a 99 JDM ITR motor. The ECU for the ITR is 2a and my car is 2b. Do any of you know how to wire this?

are you sure you want to run the JDM ITR ECU???

im pretty sure it has an imobiliser in it (car wont start without a chipped key that is registered to the ECU)
JDM ECUs have a 112mph speed limiter on them (you will reach speeds higher than this if you track the car)

this would be best, i did tell you about hondata awile ago but you might not need it unless your real serious about tracking the car. a vafc and chipped p28 you could have tuned at a shop to give you good numbers but ofcourse the hondata is better overall.

FYI the ITR 99 ECU is OBD2B not OBD2a. I know someone with a 99ITR in his 99 EX and just used a 00 SI harness and verything worked fine.

so why did your friend use the 00 si harness then? because it doesnt plug in.
