ok..my 92 si hatch currently has a h23a1 in it and im going to swap in a jdm h22a in this weekend. My question is that can I use the wire harness off of the jdm h22a or do I need to use the usdm civic or the one that my h23a1 is currently using? I'll be using a p13 ecu so I need to wire up the knock sensor, right? Other than that, will there be anything that I must do. From what I'm feeling, it should be pretty much plug and play since my eg is already setup for an H-series. Thanks in advance for any positive feedback.
