I have the jumper harness but its for the big plug. I was gonna say you can have it cause I dnt need it. Its still brand new. I'm never gonna use it. I'm a just buy an obd1 harness and convert my car much less work

or is the harness...... if it is do what this dude did and bypass it, run to the pinout on the ecu

99-00 SOHC civic's use a smaller OBD1 style dizzy plug, whereas all 96-01 OBD2 integra/B-series engines use a bigger dizzy plug, same kind of dizzy plug that all 96-98 SOHC civic's use.

All you need to do is convert your 99 EX's dizzy plug (EWH side) to the 97 GSR dizzy plug by color matching the wires. Being that your SOHC dizzy is missing 1 wire, don't worry, the car will run and your tach will work. Ignore the fact 1 dizzy wire is missing altogether.
