Hi everyone, I have a 97 Accord Ex Auto. I am going to be doing an H22A4 swap here in a few months. I have ran into one problem the 97-01 prelude ecu uses a seperate TCU. The Accords TCU is intergrated into the Ecu already. Please note these both are a OBD2a system, not OBD1. So do I need the prelude ecu/tcu harness? I already have a P5M w/the immobilizer mod and already have the seperate Prelude TCU.

 

there might be a jdm ecu for the accord which will run h22 motors
