hey guys i have an ek but going to trade for an eg shell..my question is would a 98 obd2a wireharness work on a 2000 obd2b motor? im asking beacause i was told that i would need a harness adater that goes from obd2 to obd1. so basically would using a 98 wire harnes be plug and play?

 

If your using an obd2 ecu,The stock harness will need alot of involved modifications.If the ecu you are using dont have the same plugs and the stock civic ecu,you should buy an adapter harness to cut down on problems.
