I'm new to this site any now I need some help. I have a 98 civic dx. I got a good deal on a 2000 ls swap w/64k. I want to stay obd2a, that is my priority. I know I can re-use my stock wiring harness, just need to extend some wires. My question is do I need anything besides an obd2a ls distributor and ecu to 'change' that motor to obd2a? Is there anything else that is different?
