Notes

  • The wire colors can vary from the diagram shown above. It is only important that the wires are connected to the correct points.

  • The A row in the Amp Mod U block (the black rectangular connector) is always on the KEY side of the connector.

  • Pin 1 is indicated with an arrow embedded in the plastic of the Amp Mod U block.

  • A wire from A1 to pin 6 is not required for this bender. Some cables will not include that wire.

  • The wire going into B3 is the wire that indicates if the bender is ON or OFF. Pin B3 outputs between 5 and 10 volts DC. If the bender control is ON, then the DSR signal at the Benderlink computer's COM port will show ACTIVE.
