Hello folks...I'm new to the eg hatch (just bought last weekend and is a shell) and new to the H22a motor! I previously owned a 99 civic si so am familiar with the general vtec stuff...the issue is I am interested in doing an h22 swap into my eg hatch and have researched the swap pretty extensively...I understand everything completely except for the wiring harness. I see ppl saying you have to modify the harness etc. My civic only has a body harness right now...cant i just use an obd1 h22a harness out of a prelude instead of buying and modifying an obd1 civic harness... someone please explain!!!
