We own several OBD2 Scanners that attach to DB9,s.

A project we are doing requires us to pinout 2 OdbII (j1962/male) connectors to ethernet (RJ45).

I am trying to pinout the Obd2 to ethernet with no luck

anyone that can kindly assist us with the pinout for that?
Below is how we connected a DB9. ( FYI )
