This jumper harness was designed to make putting a Honda K series into a late model (1989 and up) E30 easy. You will only have to wire in one standard relay so the ECU can control your radiator fan. We will need to know what year your car to ensure the harness will work for you. You will need a stock or aftermarket K series engine harness. (02-04 RSX) please email what year your car is to fucatypr7393@gmail.com
