    84 eta m30b35 wiring

    I have pinouts for both cars, and have already spliced most of the c101 to the former x20 wires except for two. Can anybody tell me which wires on the m30 harness pins 6 and 17 are spliced to from the c101? Those are the only two I need to finish up the harness.

      Looks like pin #6 is the "Voltage with Ignition ON", it's Green/White
      Pin #17 is TXD, I'm not sure what it is used for though. The car runs without it. It's the white/violet wire. I'm pretty sure the only pins you need to add are the Fuel Rate (white or black/white #3), Engine speed (black #9), and possibly give coil power to the fuel cut code wire in the glovebox (green/red). The last part is a little fuzzy in my memory I could be wrong about that. I have a chart in my profile.

        Thanks a lot, I'll take a look at it. Seemed like I needed to splice more wires than just what I had at the c101
