I have a 1988 civic CRX SI. I'm putting a 1999 civic B16 A2 motor in the crx. I need to make sure, but I need the OBDO to OBD1 cpu harness, correct?


Also, do you guys have any tips for when I swap out the motors?

 

Your running it as obd1 right? Then you do need a jumper harness for your ecu. Here's a tip: when your pounding on your axles trying to get them out of the hub, LEAVE THE NUT ON! Don't mushroom the threads

 

Yeah, I think that is the best way to go.
