Here's the pinout of the Dataconnector IN a Honda ECU:

  • 1: GND
  • 2: RX (send Data from the PC to the ECU)
  • 3: +5 Volt
  • 4: TX (send Data from ECU to the PC)
  • 5: N.C. (not connected)

This port is half-duplex (RX and TX are connected) in stock form. See OBD1 J12 for more information about full-duplex modification.
