    C101 square plug with M52 swap... will M50 adapter work?

    So I have a 84 325e that I am doing an M52 swap with.
    I have the M52 harness and ECU.
    The E30 has a square C101 plug.
    Somebody is selling a square C101 to M50 harness adapter.
    Will this work with my M52 harness?

    X20 pinouts are different between M50 and M52

      These should be the relevant pinouts if you're interested. Thanks to Kadunza for making these.

          square adapters are basically impossible to make because the engine side connector housing is NLA. If you want to remove it off your original engine harness, I'm sure one of the people who make adapters could do it.

            Garagistic 3D prints new engine side square plugs.
