Relay contact Pin 6. 8) With a meter or circuit tester, check that NO CONNECTION BETWEEN THE PHONE WIRES AND THE JOYSTICK WIRES!.Cross check all 4 wires! 9) Package up, to protect the unit and install into Joystick port 2. 10) Plug the unit into the phone jack. You may need a Y-Connector. 11) You are now ready to run your software. CATION! Failure to Build and install correctly CAN AND WILL DAMAGE YOUR COMPUTER!
