Hello, how are you, I have some questions, The RX7 1993 FD3S what OBD system is??? OBD1 or OBD2? also, I wnat to know where is located this connector in tha car thank you

 

It's OBD nuthin' . There is a diagnostic port under the hood, but it's for a Mazda-only code scanner that's VERY expensive.

But, you can get engine codes by using a jumper wire - this is documented in the FAQ at the top of the forum.

It is OBD-1, which is how you can get Codes from the scanner. I answered this already in your other thread!

Please read here for the Code procedure: http://www.fd3s.net/engine_codes.html
