What kind of transmission? The purple wire comes from the neutral safety switch (either in the console or on top of the steering column) or the clutch switch if you have a manual transmission. 12V power comes from the ignition switch to the other side of the neutral safety switch or clutch switch. The wire should only be hot with the key in the start position.
The yellow wire runs from the starter to the ignition coil and supplies 12V directly to the coil during starting to get a hotter spark. The orange wire goes to the fan motor. The black one goes to the oil pressure switch on the top of the motor, the blue and light blue goes to the wiper motor.
