I putting an HMO B16A OBD1 swap into a 98 Civic EX and would like to buy a jumper harness somewhere so I don't have to mess around with the wiring. Obviously I want to back date the car. So what legit site can I buy it from?

I've always used a guy on Ebay. His user is JDM1810 or JDM1815. He is very cheap on harnesses and most of his harnesses use OEM (AMP) plugs. In case you did not know, you need an OBD2A to OBD1 conversion harness.

BTW: an alternative to getting the conversion harness would be to get a 96-97 del Sol VTEC (B16A3) ECU. You would simply have to do the CKF bypass since your engine does not have the provision for the Crankshaft Fluctuation Sensor. 5 minute deal to do the CKF bypass and you still have OBD2 diagnostics on board. I'd only go to OBD1 if you intend on having the car tuned. By tuned, I don't mean buying a chip on Ebay....

Thanks bro good info,

real quick what throttle cable do I use? Stock or 99-00 Si?

RyanA

99-00 Si cable and throttle bracket. Throttle bracket will have P2T on it. The regular B16 one on your engine right now MAY work but, to be safe, I'd get the 99-00 one.

Buy the conversion harness from jhpusa.com I heard alot of the ebay wires come loose very easy.

Yes, you are right. That is why you want to only buy conversion harnesses that use OEM Honda connectors. If they have some cheap trash plugs, they can definitely make you mad. I have a friend that got a cheap conversion harness and his car would miss. Come to find out, when you wiggled the conversion harness, it would start hitting on all 4 again. It ended up being one of the injector wires was getting an intermittent connection.

had the exact same problem with a cheap harness
