Ok I have a 91 crx dx. converted over to MPFI. Then I have OBD1 on it and the only code it is throwing is the O2 code. For some reason I can't figure out the o2 wiring. They say I have to run the wires to D14 and D22. But hwere is that at. I only have three plugs. A B and C. Wheres D?
If I could find that out that would be great. Sorry about all the posts. I was pissed last night. I will delete some of them.

Ok i have a new question. Where is sam hell is D14. I am really pissed off right now and I need some freaking help. Thanks. Has anyone switched there car from obd0 to obd1 with the hasport harness. For some reason i cant get the o2 code to go away. Heres what I have. DX crx to MPFI. D16z6 engine. hasport shorty harness for the obd0 to obd1 conversion. I have directly wired the o2 sensor up to the ecu but that didn't work. Does the o2 have to read the temp sensor, tps, and the coolent temp. I have the heater code gone so that can't be it. could someone tell me how to wire this would be good.

thanks guys. its for a friend that wants to cry, his car has been throwing codes for years.

bump for the o2 sensor code. and how do you get rid of it?

If you converted over to obd1 did you use a harness converter? If so you need a 4 wire o2 to work with your obd1 ecu. Be more specific about your setup and I'm sure we can help.
