did any fc's come with an obd2 outlet? or did they all just come with the mazda green connectors under the hood?

just curious because i saw a 89 rx7 with an obd2 port and the guy swears its all original. smells fishy to me.

thanks

ObdII wasn't even a thought when these cars came out. A few 95 cars and all 96+ cars are obdII

ODB2 first started coming out in '92, was standard in '96

Uhh you know those green diagnostic connectors in the engine bay on FCs? Those are technically ODB (one, not two). ODB was a massive failure because it allowed manufacturers to specify everything. The codes, the connectors, etc. ODB's failure paved the way for ODB2 which standardized the connector, certain interfacing functions, and a specific set of codes and their meanings.

^it wasn't even referred to as OBD "I" though until OBD "II" mandated for '96

Kind of like World War One wasn't called that until the second happened.

MAZDATRIX and MAZDA sell/sold a box you plugged into the six socket green connector in the engine bay and that gave you the codes/faults present. Not worth the money when you can buy two LED lights and do the same thing for five bucks or less.

don't forget their special device thing that plugged in between the ECU and the harness.

Maybe it might be possible to figure the pins out???

maybe convert the green plug to a obd plug??? Just an opinion

Not realistically possible. Would take too much R+D time and money for basically no gain. Would be easier to strip out the ECU, all the sensors, the entire wiring harness, and replace all of it with a brand new system,
