Thanks for the info. The problem I have is that I have a complete 97 sohc motor with ecu and engine harness and I was told it would fit and plug up and start in my 99 ek. I got the harness because old one was missing some plugs and ecu plugs were all cut up. The main question I have is can i go to a junk yard, buy the fourth harness plug, and rewire it to work in my 99 ek. I believe the fourth plug is the one from the dash(the plug that is not attached to the engine harness) Oh and my axles are from a 93 civic, they should fit into my ek too right?
