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 )

this doesn't tell you what wires from the rj45 connect to the obd2 im in Australia and looking at that link tells me nothing

It tells you everything you need to know, to save you the trouble here it is.

V2 RJ-45
1 - 12V
2 - CAN + (H)
3 - CAN - (L)
4 - GND
6 - VPW
8 - GND

OBDII plug
2 - VPW
4 - GND
5 - GND
6 - CAN - (L)
14 - CAN + (H)
16 - 12V

But if you are just going from RJ45 to OBD-II then why not use the supplied cable?
