  • 2x2 to obd connection

    So, i am closing in on completion of my wiring hell. I am down to dealing with the diagnostic lines. I have a question about the 2x2 to obd adapters.

    is there signal modification in those adapters?

    I ask because i looked up the adapter for my ross tech cable and the adapter is $50. No big deal.

    shipping is $100.

    On principal alone i say eff that, i will make my own adapter..... but i dunno if it's a straight connection or if there's magic in the adapter.

    if anyone could confirm for me that would be great!

    Have a look at this post. It might be worth your while doing when you have everything apart.

    Or just get an adaptor cable of Amazon for a lot less than RossTech

        It's definitely just 4 wires connected to the 16 pin plug.
