I have a 5 speed 99 ek hatch, i also have a 2000 ITR motor that i would like to put into it. I am told that i can get a 99-01 civic si/ex engine harness and it will be plug and play. I can handle that, NOW, I have a ITR ecu, and also a chipped p28 ecu. Would i be able to run the ITR ecu? Should i get a obd2-0bd1 jumper harness and plug up the p28? I'm just curious as to wat i should do about an ecu. I searched the [FAQ] ECU thread. Codes, wiring pinouts and more. New and Improved Ecu thread BUT did not find my answer,
Thankyou in advance!

 

dont know about eks and the whole harness thing but i know for egs all you have to do is wire it for vtec.

as for the ecu i would use the itr

 

so the ITR ecu will plug up in the ek right now? If not then what do i have to do to run the ITR ecu. And then i will just wire the motor with a 99-01 civic ex/si harness, and then i shouldn't have to run any wires for vtec correct?

 

OR is it possible to have a 99-01 integra harness and run it through the firewall? Then will the three plugs plug into that ecu and ruN?
